Light Charged And Neutral Particle Production In Proton And Alpha Reactions On Si-Nat At Energies Between 20 And 65 Mev

Measurements have been performed to determine inclusive cross sections (d(2)sigma/d Omega dE, d sigma/dE, d sigma/d Omega and sigma(tot)) 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 Si-nat targets. The secondary LCPs (p, d, t, He-3, alpha, Li-6, Li-7 and Be-7) were detected at angles from 10 degrees to 165 degrees in steps of +/- 10 degrees. 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.
