Damage calculations at high ion energy-part II

Abstract

Abstract A method is presented for damage energy distribution calculations for incident energies above the electronic stopping power maximum. The method is based on the approximate solution of the transport equation for stationary angular flux developed in a previous paper. In order to compare the results with experimental data and other theoretical rates, calculations were made at incident energies under the electronic stopping power maximum (for Al ions at 4.6, 5 and 5.4 MeV incident energies in Al target and for 46.7 MeV Ni in Au target). Combining the large energy transfer approximation and the path length approximation, we obtain a simple approximation for the calculation of the “tail” of the damage rates at high incident energies.
