A study of the reaction ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}$${(}^{20}$Ne${,}^{19}$Ne 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 ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}$ is maximal in the forward direction. Comparisons with calculated neutron angular distributions show the effect of the final state interaction.
