Abstract
Inclusive cross sections ( d 2 σ, d Ω dE , d σ dE , d σ d Ω and σ T ) for the production of light charged particles induced by protons of 26.5, 48.5 and 62.9 MeV and alpha-particles of 25.4, 45.5 and 57.8 MeV on nat Si targets have been measured. The secondary emitted particles ( p , d , t , 3 He , α, 6 Li , 7 Li and 7 Be ) were detected at angles from 10° to 165° in steps of ±10° with respect to the beam axis. Neutrons emitted in these reactions were only recorded in coincidence with, at least, one detected light charged particle. The measurements were compared with all available published data from similar or comparable reactions and with theoretical calculations based on the GNASH and TALYS nuclear-reaction codes.
