Abstract

A study of the reaction Ca-48(Ne-20,Ne-19 n) at 48A MeV has been performed at the GANIL facility. The inclusive excitation spectrum above 12 MeV excitation is dominated by a broad structureless bump. Calculations performed in the framework of the Bonaccorso-Brink model predict that the absorption process (transfer +inelastic breakup) dominates over the elastic breakup process. Comparison of the neutron multiplicity calculated in a statistical model with the measured one confirms a significant contribution of the direct processes (elastic and inelastic breakup). The neutron yield to the ground state of the Ca-48 is maximal in the forward direction. Comparisons with calculated neutron angular distributions show the effect of the final state interaction.
