Article: Superdeformation in Asymmetric N$>$Z Nucleus $^{40}$Ar
[show abstract] [hide abstract]
ABSTRACT: A rotational band with five $\gamma$-ray transitions ranging from 2$^{+}$ to 12$^{+}$ states was identified in $^{40}$Ar. This band is linked through $\gamma$ transitions from the excited 2$^{+}$, 4$^{+}$ and 6$^{+}$ levels to the low-lying states; this determines the excitation energy and the spin-parity of the band. The deduced transition quadrupole moment of 1.45$^{+0.49}_{-0.31} eb$ indicates that the band has a superdeformed shape. The nature of the band is revealed by cranked Hartree--Fock--Bogoliubov calculations and a multiparticle--multihole configuration is assigned to the band.10/2009; -
Article: Dipole bands in 142Gd
[show abstract] [hide abstract]
ABSTRACT: The high spin states of 142Gd were studied via the 111Cd(35Cl,1p3n) reaction at 170 MeV. Three dipole cascades were found, one of which decayed to both the proton high-j particle states and the neutron high-j hole states. These can be classified in the category of "Shears Band" which is introduced by S. Frauendorf.Zeitschrift für Physik A Hadrons and Nuclei 05/1997; 358(1):1-2. -
Article: A γ-ray detector array for joint spectroscopy experiments at the JAERI tandem–booster facility
[show abstract] [hide abstract]
ABSTRACT: A compact array for γ-ray spectroscopy developed for the joint experiment at the Japan Atomic Energy Research Institute is described. It consists of an array of 11 Compton suppressed Ge detectors, a 4π silicon detector array for charged particle measurements, a position-sensitive silicon detector for experiments on Coulomb excitation and a conversion-electron spectrometer. The details of the detectors and new experimental results obtained with the compact array are also described.Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. -
