Effect of Intranuclear Cascades on the Composition and Energy of Fragments Originating from Si(\({p,x}\)) and Fe(\({p,x}\)) Nuclear Reactions


Quantum-mechanical models and the Monte Carlo method are used to study the composition and energies of products of nuclear reactions induced by collisions of fast protons with silicon and iron nuclei. It is shown that, at proton energies in excess of 500 MeV, intranuclear cascades at the stage of compound-nucleus formation in a preequilibrium state lead to an increase in the number of secondary ions and to a decrease in their average energy. The respective calculations were performed by means of the TALYS, EMPIRE, GEANT4, and FLUKA code packages.
