Abstract
The nuclear collision O18+Ca40 at 275 MeV is theoretically studied in the elastic, inelastic, one-nucleon transfer, and charge-exchange channels. The elastic scattering channel is treated within the optical model framework with the help of semimicroscopic double folding potentials, which are constructed by using the realistic nuclear matter densities obtained within the Hartree-Fock-Bogoliubov method, while the distorted wave Born approximation method is adopted to calculate differential cross sections for the other channels. The charge exchange nuclear reaction Ca40(O18, F18)K40 is analyzed by assuming the two-step transfer mechanisms, namely by considering a succession of proton-neutron pickup-stripping processes. Large-scale shell-model calculations are employed to compute the spectroscopic amplitudes, needed in our approach. When compared to the available experimental angular distributions, the obtained results show that the two-step transfer mechanisms play a relevant role in the description of the Ca40(O18, F18)K40 reaction and need to be accounted for in any accurate analysis of the measured cross section.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
