Model study of composite particle production in medium-energy nuclear reaction

The intranuclear cascade model is investigated to explain composite particle productions in medium-energy proton-nucleus reactions. The composite particle production is governed mainly by the direct pick-up process in the medium-energy range. In the present work, the direct pickup process is introduced into the model in addition to the knockout and the indirect-pickup processes. Resultant double differential cross sections for proton-induced reactions are in good agreements with experiments over the entire energy range.
