Light charged and neutral particle production in proton and alpha reactions on natSi at energies between 20 and 65 MeV

Measurements have been performed to determine inclusive cross sections (d2σdΩdE, dσdE, dσdΩ and σtot) for the production of neutral and light charged particles (LCP) induced by beams of protons of 26.5, 48.5 and 62.9 MeV and alpha’s of 25.4, 45.5 and 57.8 MeV incident energies on natSi targets. The secondary LCPs (p, d, t, 3He, α, 6Li, 7Li and 7Be) were detected at angles from 10° to 165 ° in steps of ±10°. Neutrons emitted in these reactions were only recorded in coincidence with, at least, one detected LCP. Some comparisons between theoretical calculations based on the GNASH and TALYS nuclear reaction codes and the experimental results are presented and discussed.
