Inclusive cross sections (d/sup 2/ sigma , d Omega dE, d sigma dE, d sigma d Omega and sigma /sub 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 /sub nat/Si targets have been measured. The secondary emitted particles (p, d, t, /sup 3/He, alpha , /sup 6/Li, /sup 7/Li and /sup 7/Be) were detected at angles from 10 degrees to 165 degrees in steps of +/-10 degrees 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.
