NUCLEAR-REACTIONS EXCITATION-FUNCTIONS AT PROTON INTERACTIONS WITH SILICON

Excitation functions of nuclear reactions promoting formation of radio active and stable isotopes during interaction of protons with E(p) les s-than-or-equal-to 100 MeV and Si have been studied. Experimental data were summarized and excitation functions calculated regarding the mec hanisms of preequilibrium emission and evaporation of particles from t he compound nucleus based on ALICE LIVERMORE code. It is shown that th is model predicts cross sections of the nuclear reactions Si(p, xn yp zalpha)B for B = P, Si, Mg, Na with accuracy to coefficient 2. To deve lop the procedure of silicon transmutation doping transmutation coeffi cients for Al, Mg, Na have been calculated as well as gamma-activities of the doped material.
