The effect of different ion stopping models on calculated parameters of the radiation damage of materials

Direct numerical solution of the Boltzman transport equation for incident ions and knocked-off atoms of the target is applied for range and damage calculations. The influence of physical parameters in a model of ion stopping in matter on the obtained range and damage distribution is investigated in the range of ion energies from 1 KeV to 1 MeV. All the examined interatomic potentials give close values of mean depths and higher moments of range and damage distributions. The influence of differences in electronic stopping is also studied. The obtained results are compared with experimental data and the results of other calculations.
