Abstract [en]

The total reaction cross section is an essential quantity in particle and heavy ion transport codes when determining the mean free path of a transported particle. Many transport codes determine the distance a particle is transported before it collides with the target, or is stopped in the target material, with the Monte Carlo (MC) method using semi-empirical parameterization models for the total reaction cross sections. In order to improve the well-known Kox and Shen models of total reaction cross sections, and allow the models to be used at energies below 30 MeV/nucleon, we propose a modified parameterization of the transparency parameter. We also report that the Kox and Shen models have a projectile-target asymmetry and should be used so that the lighter nucleus is always treated as the projectile.
