Preequilibrium Models for ⁶³Cu(n, xp) Reaction in Neutrons at 9, 11, 14.8, and 15 MeV Using the EMPIRE 3.2 Code

In this study, the calculations of proton emission spectra and of the excitation function produced by ⁶³Cu(n, xp) and ⁶³Cu(n, p)⁶³Ni reactions, respectively, are used in the framework of preequilibrium models with the new version of the EMPIRE 3.2 code. Exciton Model predictions combined with the Kalbach angular distribution systematics and the Hybrid Monte Carlo Simulation (HMS) were used, and some necessary parameters have been investigated for our calculations. The comparison with experimental data shows clear improvement over the Exciton Model and HMS calculations.
