THE ION-ION POTENTIAL AND NEUTRON TRANSFER PROCESSES IN THE O-18-58,NI-60 SYSTEMS AT SUBBARRIER ENERGIES(NI)

Recently we have presented a realiable determination of the ion-ion po tentials for the O-16+Ni-58,Ni-60,Ni-62,Ni-64 systems, at the large in teracting radius (9.5 less than or equal to R less than or equal to 11 .5 fm), by measuring the elastic (1% precision) and inelastic (2(+)) c ross sections at sub-barrier energies. In the present work, we have ex tended those studies to the O-18+Ni-58,Ni-60 systems, and we have inve stigated: (i) the influence of the neutron-transfer processes in the d etermination of the ion-ion potentials using the coupled-channel (CC) analysis of the data, (ii) the comparison between the resulting CC ion -ion potentials and the theoretical calculations using the double-fold ed method and shell-model densities, (iii) possible influence of the t wo-neutron transfer process in the measured fusion cross sections for the O-16,O-18+Ni-58,Ni-60.
