Abstract:

This study concerns the development of nuclear spallation models to allow the prediction of gamma rays and neutrons emitted in the backward directions from thick targets of various material compositions when bombarded by various types of ions hydrogen through lithium in the energy range from about 50 MeV to several hundred MeV. A theoretical high-energy nuclear interaction model the intranuclear-cascade-evaporation model is extended to treat secondary particle production from ion beam collisions, and this model is incorporated in thick-target radiation transport computer codes. Monte Carlo methods are used in computing both the nuclear interaction products and the radiation transport. Example results from applying these models are given for various ions bombarding an aluminum target.
