Preequilibrium models for Ni (n, xp) and Ni (n, xp) reactions in neutrons at 8, 9, 9.4, 11 and 14.8 MeV using the EMPIRE and TALYS codes.

In this study, the calculations of proton emission spectra produced by Ni (n, xp) and Ni (n, xp) reactions are used in the framework of preequilibrium models with the EMPIRE and TALYS codes. Exciton Model predictions combined with the Kalbach angular distributions systematics, quantum-mechanical preequilibrium models (Multi-step Direct (MSD) theory and Multi-step Compound (MSC) processes) were used, and some necessary parameters have been investigated for our calculations. The comparison with experimental data shows clear improvement over the Exciton and quantum-mechanical preequilibrium models calculations.
