Monte Carlo simulation of kilovolt positron penetration and backscattering probabilities in solids

Abstract

Monte Carlo simulations of the backscattering probabilities, mean penetration depths and implantation profiles of positrons for elemental solids are reported as a function of atomic number 4 less than or equal to Z less than or equal to 82 and incident energies from 5 to 70 keV. It is demonstrated that backscattering probability and mean penetration depth values can be estimated reliably by using a simple Monte Carlo code for different incident energies and angles. The simulation results are in general in good agreement with other simulations and experiments.
