ABSTRACT: A detailed study of known and new SD bands in Tb isotopes has been performed with the use of the EUROBALL IV gamma-ray array. The high-statistics data set has allowed for the extension of known SD bands at low and high spins by new gamma-ray transitions. These transitions, as it turns out, correspond to the rotational frequencies where the principal superdeformed gaps (Z=66,N=86) close giving rise to up- or down-bending mechanisms. This enables to attribute the underlying theoretical configurations with much higher confidence as compared to the previous identifications. Five new SD bands have been discovered, three of them assigned to the 152Tb and the two others to the 151Tb nuclei. Nuclear mean-field calculations have been used to interpret the structure of known SD bands as well as of the new ones in terms of nucleonic configurations.

ABSTRACT: The decay of ^{19}O(β^{-}) and ^{19}Ne(β^{+}) implanted in niobium in its superconducting and metallic phases was measured using purified radioactive beams produced by the SPIRAL GANIL facility. Half-lives and branching ratios measured in the two phases are consistent within a 1σ error bar. This measurement casts strong doubts on the predicted strong electron screening in a superconductor, the so-called superscreening. The measured difference in screening potential energy is 110(90) eV for ^{19}Ne and 400(320) eV for ^{19}O. Precise determinations of the half-lives were obtained for ^{19}O, 26.476(9) s, and for ^{19}Ne, 17.254(5) s.

ABSTRACT: The decay of $^{19}$O($\beta^-$) and $^{19}$Ne($\beta^+$) implanted in
niobium in its superconducting and metallic phase was measured using purified
radioactive beams produced by the SPIRAL/GANIL facility. Half-lives and
branching ratios measured in the two phases are consistent within one-sigma
error bar. This measurement casts strong doubts on the predicted strong
electron screening in superconductor, the so-called superscreening. The
measured difference in screening potential energy is 110(90) eV for $^{19}$Ne
and 400(320) eV for $^{19}$O. Precise determinations of the half-lives were
obtained for $^{19}$O: 26.476(9) s and $^{19}$Ne: 17.254(5) s.

ABSTRACT: The level structures of the N = 50 83 As, 82 Ge, and 81 Ga isotones have been investigated by means of multi-nucleon transfer reactions. A first experiment was performed with the CLARA–PRISMA setup to identify these nuclei. A second experiment was carried out with the GASP array in order to deduce the γ -ray coincidence information. The results obtained on the high-spin states of such nuclei are used to test the stability of the N = 50 shell closure in the region of 78 Ni (Z = 28). The comparison of the experimen-tal level schemes with the shell-model calculations yields an N = 50 energy gap value of 4.7(3) MeV at Z = 28. This value, in a good agreement with the prediction of the finite-range liquid-drop model as well as with the recent large-scale shell model calculations, does not support a weakening of the N = 50 shell gap down to Z = 28.: NUCLEAR REACTIONS 238 U(82 Se, 81 Ga), (82 Se, 82 Ge), (82 Se, 83 As), E = 515 MeV; measured E γ , I γ (θ), γ γ -coin, reaction fragments, (fragment)γ -coin using PRISMA magnetic spectrometer, γ after deexcitation using Ge Compton-suppressed detectors of CLARA array, thin and thick target; deduced σ (θ), levels, J , π ; calculated levels, J , π using shell model

ABSTRACT: The shell structure of atomic nuclei is associated with 'magic numbers' and originates in the nearly independent motion of neutrons and protons in a mean potential generated by all nucleons. During β(+)-decay, a proton transforms into a neutron in a previously not fully occupied orbital, emitting a positron-neutrino pair with either parallel or antiparallel spins, in a Gamow-Teller or Fermi transition, respectively. The transition probability, or strength, of a Gamow-Teller transition depends sensitively on the underlying shell structure and is usually distributed among many states in the neighbouring nucleus. Here we report measurements of the half-life and decay energy for the decay of (100)Sn, the heaviest doubly magic nucleus with equal numbers of protons and neutrons. In the β-decay of (100)Sn, a large fraction of the strength is observable because of the large decay energy. We determine the largest Gamow-Teller strength so far measured in allowed nuclear β-decay, establishing the 'superallowed' nature of this Gamow-Teller transition. The large strength and the low-energy states in the daughter nucleus, (100)In, are well reproduced by modern, large-scale shell model calculations.

ABSTRACT: We investigated deep inelastic reactions in 238U + 238U collisions at 6.09, 6.49, 6.91, 7.1 and 7.35×A MeV at the VAMOS spectrometer (GANIL). A large transfer of neutrons and protons was observed at all beam energies. For a
transfer of more than 10 nucleons the total kinetic energy of the detected fragments becomes independent of the beam energy
and reaches values far below the Coulomb barrier for spherical fragments. This points to the formation of a di-nuclear system
in the entrance channel which develops an elongated shape and a strong neck. For such reactions we expect an enhanced lifetime
of the di-nuclear system which is significantly longer than the time scale for elastic and quasi-elastic reactions. Different
theoretical approaches predict delay times of more than 5×10-21 s for a subset of our data.

ABSTRACT: We report on the observation of a new isomeric state in $^{68}$Ni. We suggest
that the newly observed state at 168(1) keV above the first 2$^+$ state is a
$\pi(2p-2h)$ 0$^{+}$ state across the major Z=28 shell gap. Comparison with
theoretical calculations indicates a pure proton intruder configuration and the
deduced low-lying structure of this key nucleus suggests a possible shape
coexistence scenario involving a highly deformed state.

ABSTRACT: The Advanced GAmma Tracking Array (AGATA) is a European project to develop
and operate the next generation gamma-ray spectrometer. AGATA is based on the
technique of gamma-ray energy tracking in electrically segmented high-purity
germanium crystals. This technique requires the accurate determination of the
energy, time and position of every interaction as a gamma ray deposits its
energy within the detector volume. Reconstruction of the full interaction path
results in a detector with very high efficiency and excellent spectral
response. The realization of gamma-ray tracking and AGATA is a result of many
technical advances. These include the development of encapsulated
highly-segmented germanium detectors assembled in a triple cluster detector
cryostat, an electronics system with fast digital sampling and a data
acquisition system to process the data at a high rate. The full
characterization of the crystals was measured and compared with
detector-response simulations. This enabled pulse-shape analysis algorithms, to
extract energy, time and position, to be employed. In addition, tracking
algorithms for event reconstruction were developed. The first phase of AGATA is
now complete and operational in its first physics campaign. In the future AGATA
will be moved between laboratories in Europe and operated in a series of
campaigns to take advantage of the different beams and facilities available to
maximize its science output. The paper reviews all the achievements made in the
AGATA project including all the necessary infrastructure to operate and support
the spectrometer.

ABSTRACT: Lifetimes of the $9/2^-_1$ and $3/2^-_1$ states in $^{63}$Co and the
$9/2^-_1$ state in $^{65}$Co were measured using the recoil distance Doppler
shift and the differential decay curve methods. The nuclei were populated by
multi-nucleon transfer reactions in inverse kinematics. Gamma rays were
measured with the EXOGAM Ge array and the recoiling fragments were fully
identified using the large-acceptance VAMOS spectrometer. The E2 transition
probabilities from the $3/2^-_1$ and $9/2^-_1$ states to the $7/2^-$ ground
state could be extracted in $^{63}$Co as well as an upper limit for the
$9/2^-_1\rightarrow7/2^-_1$ $B$(E2) value in $^{65}$Co. The experimental
results were compared to large-scale shell-model calculations in the $pf$ and
$pfg_{9/2}$ model spaces, allowing to draw conclusions on the single-particle
or collective nature of the various states.

ABSTRACT: We report here the first direct lifetime measurement of the 21+ state in 72,74Zn. The neutron-rich beam was produced by in-flight fragmentation of 76Ge at the Grand Accélérateur National d'Ions Lourds and separated with the LISE spectrometer. The 21+ state was excited by inelastic scattering and knock-out reaction on a CD2 target and its lifetime was measured by the recoil-distance Doppler-shift method with the Köln plunger device combined with the EXOGAM detectors. The lifetimes of the 21+ states in 72,74Zn were determined to be 17.9(18) and 27.0(24) ps, which correspond to reduced transition probabilities B(E2;21+→0+)=385(39) and 370(33) e2 fm4, respectively. These values support the idea of a systematic maximum of collectivity at N=42 for Zn, Ge, and Se nuclei. In addition, the available systematics in the neighboring nuclei point toward a transition from a spherical oscillator at N=40 to complete γ-softness at N=42.

ABSTRACT: Direct observation of the survival of 199Au residues after 2n transfer in the system and the absence of the corresponding 67Cu in the system at various energies are reported. The measurements of the surprisingly large cross sections for 199Au, coupled with the integral cross sections for the various Au residues, is used to obtain the first model-independent lower limits on the ratio of 2n to 1n transfer cross sections from 8He to a heavy target. A comparison of the transfer cross sections for 6,8He on these targets highlights the differences in the interactions of these Borromean nuclei. These measurements for the most neutron-rich nuclei on different targets highlight the need to probe the reaction mechanism with various targets and represent an experimental advance towards understanding specific features of pairing in the dynamics of dilute nuclear systems.

ABSTRACT: Shell structure and magic numbers in atomic nuclei were generally explained by pioneering work that introduced a strong spin-orbit interaction to the nuclear shell model potential. However, knowledge of nuclear forces and the mechanisms governing the structure of nuclei, in particular far from stability, is still incomplete. In nuclei with equal neutron and proton numbers (N = Z), enhanced correlations arise between neutrons and protons (two distinct types of fermions) that occupy orbitals with the same quantum numbers. Such correlations have been predicted to favour an unusual type of nuclear superfluidity, termed isoscalar neutron-proton pairing, in addition to normal isovector pairing. Despite many experimental efforts, these predictions have not been confirmed. Here we report the experimental observation of excited states in the N = Z = 46 nucleus (92)Pd. Gamma rays emitted following the (58)Ni((36)Ar,2n)(92)Pd fusion-evaporation reaction were identified using a combination of state-of-the-art high-resolution γ-ray, charged-particle and neutron detector systems. Our results reveal evidence for a spin-aligned, isoscalar neutron-proton coupling scheme, different from the previous prediction. We suggest that this coupling scheme replaces normal superfluidity (characterized by seniority coupling) in the ground and low-lying excited states of the heaviest N = Z nuclei. Such strong, isoscalar neutron-proton correlations would have a considerable impact on the nuclear level structure and possibly influence the dynamics of rapid proton capture in stellar nucleosynthesis.

ABSTRACT: The spectroscopy of 21O has been investigated using a radioactive 20O beam
and the (d,p) reaction in inverse kinematics. The ground and first excited
states have been determined to be Jpi=5/2+ and Jpi=1/2+ respectively. Two
neutron unbound states were observed at excitation energies of 4.76 +- 0.10 and
6.16 +- 0.11. The spectroscopic factor deduced for the lower of these
interpreted as a 3/2+ level, reveals a rather pure 0d3/2 single-particle
configuration. The large energy difference between the 3/2+ and 1/2+ states is
indicative of the emergence of the N=16 magic number. For the higher lying
resonance, which has a character consistent with a spin-parity assignment of
3/2+ or 7/2-, a 71% branching ratio to the first 2+ state in 20O has been
observed. The results are compared with new shell model calculations.

ABSTRACT: The transfer of neutrons onto 24Ne has been measured using a reaccelerated radioactive beam of 24Ne to study the (d,p) reaction in inverse kinematics. The unusual raising of the first 3/2+ level in 25Ne and its significance in terms of the migration of the neutron magic number from N=20 to N=16 is put on a firm footing by confirmation of this state's identity. The raised 3/2+ level is observed simultaneously with the intruder negative parity 7/2- and 3/2- levels, providing evidence for the reduction in the N=20 gap. The coincident gamma-ray decays allowed the assignment of spins as well as the transferred orbital angular momentum. The excitation energy of the 3/2+ state shows that the established USD shell model breaks down well within the sd model space and requires a revised treatment of the proton-neutron monopole interaction.

ABSTRACT: A modern variation of the Rutherford experiment to probe the tunneling of exotic nuclear matter from the measurement of the residues formed in the bombardment of (197)Au by extremely neutron-rich (8)He nuclei is presented. Using a novel off-beam technique the most precise and accurate measurements of fusion and neutron transfer involving reaccelerated unstable beams are reported. The results show unusual behavior of the tunneling of (8)He compared to that for lighter helium isotopes, highlighting the role of the intrinsic structure of composite many-body quantum systems and pairing correlations.

ABSTRACT: The Euroball array has been used to search for linking transitions between the superdeformed (SD) and the normal deformed (ND) wells in 151Tb. Many γ rays in the energy range 2–4 MeV have been observed in coincidence with the yrast SD band. It is proposed that the highest energy transition of 3748 keV and the strongest line (2818 keV) of the previously observed transitions both decay from the same SD level as their links with the ND states have been identified. The current spectra have insufficient statistics to completely identify the decay point in the SD band. Theoretical calculations covering SD bands in the A≈150 region enable the two possible spin assignments to be compared with experimental data on proposed links in 149Gd and 152Dy. It is concluded that the energy of the lowest SD band member in 151Tb has an excitation energy of 12861 keV and a spin of 65/2+.

ABSTRACT: Angular distributions for 1n and 2n transfer are reported for the 6He+65Cu system at E_{lab}=22.6 MeV. For the first time, triple coincidences between alpha particles, neutrons, and characteristic gamma rays from the targetlike residues were used to separate the contributions arising from 1n and 2n transfer. The differential cross sections for these channels, elastic scattering, and fusion were analyzed using a coupled reaction channels approach. The large measured ratio of the 2n-to-1n cross section and the strong influence of 2n transfer on other channels indicate that the dineutron configuration of 6He plays a dominant role in the reaction mechanism.
