Abstract

Two versions of the pre-equilibrium ALICE code (HMS-ALICE and ALICE-IPPE) were used to investigate the effect of various models for level density and cluster emission mechanisms on the description of reaction cross-sections with multiple-particle emission induced by protons of energy up to 200 MeV in a mass region from Mn to Bi. Comparison with experimental data shows that the generalised superfluid model for level density is preferable for nuclei far from the beta stability line. For the reactions where composite charged particles can be pro-duced, the account of both pick-up and knock-out mechanisms can be crucial for the consistent description of excitation functions in the energy region 30–80 MeV where the pre-equilibrium cluster emission and emission of several uncorrelated nucleons compete.
