A study of pre-equilibrium emission in some proton- and alpha-induced reactions

Excitation functions (EFs) for a large number of proton- and alpha-induced reactions in the energy range ≈8–60 MeV have been measured employing stacked foil activation technique. The theoretical calculations of the EFs have been carried out using the semi-classical code, which includes compound nucleus (CN) and pre-equilibrium (PE) emission into consideration. In general, the theoretical calculations agree well with the experimental data. The PE fraction has also been calculated and found to depend strongly on the energy of the incident particle.
