Monte Carlo calculation of the distributions of interatomic separation and relative velocity resulting from the dissociation of fast molecular ions by thin foils

Abstract

A Monte Carlo program to calculate the distributions of separation and relative velocity resulting from the dissociation of fast molecular ions traversing thin foils, including effects of Coulomb explosion, multiple scattering and differential energy loss, has been developed. Effects of differing single particle scattering cross sections due to different assumptions concerning the screening of target atoms have been considered. Results for H 2 + ions of 0.10, 0.15 and 0.20 MeV/amu incident upon C foils of thickness ranging from 2–15 μ/cm 2 are presented.
