Abstract
A collisionless, quasi-parallel shock is simulated using Monte Carlo techniques. In this kinetic approach, scattering of all velocity particles (from thermal to high energy) is assumed to occur such that the mean free path is directly proportional to velocity times the mass to charge ratio and inversely proportional to the plasma density. Within the constraints of this assumption, the shock profile and velocity spectra are obtained showing preferential acceleration of high A/Z particles relative to protons.
