ABSTRACT A preliminary investigation of the nuclear imaginary potential to be used for the analysis of elastic scattering data of heavy ions is presented. The derivation is carried out in the framework of the semiclassical description. The resulting potential is angular momentum independent and shows two components. A long range part due to transfer reactions and a short range part due to nuclear inelastic scattering. Coulomb excitation has not been taken into account. Simple closed expressions are derived for the transition amplitudes associated with the transfer and inelastic processes, including the Q-value dependence which can be used for the analysis of reaction data.

    ABSTRACT: Cross sections of one- and few-nucleon transfers in the reaction 28Si+ 28Si at Elab=151.25 MeV have been measured with a quadrupole-dipole-dipole-dipole magnetic spectrometer. The one-neutron and one-proton transfers to corresponding shell model states in the pairs of mirror nuclei 29-29P and 27-27Al are found to be approximately equal. The cross sections for few-nucleon transfers to states with excitation energies Ex<5 MeV exhibit a strong enhancement of 1n1p over 2n and 2p and of 2n2p (i.e., 1α) over 2n1p or 1n2p transfers. A distorted-wave Born approximation analysis of the 1n and 1p transfers was performed. The derived spectroscopic factors display a high degree of symmetry with respect to isospin and are consistent with the widely varying values obtained in light ion studies.

    ABSTRACT: Weakly populated multinucleon transfer reactions have been studied in 64Ni+238U at Elab=390 MeV with a time-of-flight magnetic spectrometer. Angular and Q-value distributions for multinucleon transfer channels have been measured up to the pickup of six neutrons and the stripping of six protons. Differential and total cross sections have been extracted and compared with calculations based on the GRAZING model for grazing reactions. The evolution of the system from a quasielastic to a more complex regime and the present limitations to a detailed understanding of these processes are discussed. The results confirm that a clear experimental distinction can be made between the collisions in the grazing (quasielastic and deep-inelastic) regime and in a more complex one (quasifission).

    ABSTRACT: Transfer reactions played a key role in unraveling many properties of the nucleus, in particular they have been essential to define the relevance of the independent particle motion and to define the properties of two-particle correlations. In view of the now available radioactive beams, it is important to summarize some aspects of the transfer processes that will be relevant to define the properties of nuclei close to the neutron and proton drip lines.
