O18+Pd110: Measurements and realistic coupled-channel analysis in a transitional region

Abstract

The inelastic, two-neutron and α transfer and quasielastic cross sections for the 18O+110Pd system have been measured in the near barrier region (40 MeV Elab 58 MeV). The experiments were performed in the S˜ao Paulo Pelletron laboratory. Coupled-channel analysis of the experimental data was performed using the S˜ao Paulo potential as a microscopic bare interaction. In the calculations, low-lying inelastic excitations, one- and two-neutron and α transfers to the target were considered as the main couplings, with no extra surface absorption. The agreement between the theoretical results and the experimental data is good. The role played by the coupled channels is very different in comparison with similar data analyses for the closed-shell region around 58Ni.
