A survey of energy loss calculations for heavy ions between 1 and 100 keV

Abstract

The original Lindhard-Scharff-Schi{\o}tt (LSS) theory and the more recent Tilinin theory for calculating the nuclear and electronic stopping powers of slow heavy ions are compared with predictions from the SRIM code by Ziegler. While little discrepancies are present for the nuclear contribution to the energy loss, large differences are found in the electronic one. When full ion recoil cascade simulations are tested against the elastic neutron scattering data available in the literature, it can be concluded that the LSS theory is the more accurate.Comment: Presented at the 10th International Symposium on Radiation Physics, 17-22 September, 2006, Coimbra, Portugal; style corrections, small change to fig.
