Abstract

Diagonal elements of the diffusion tensor for positron swarms in molecular gases under the influence of electric and magnetic fields are investigated using a Monte Carlo simulation technique and multi-term theory for solving the Boltzmann equation. The focus was on the synergetic effects of non-conservative collisions and magnetic fields on the diffusion of positrons. It is found that different diagonal elements of the diffusion tensor show different sensitivities to the strength of magnetic field and on the presence of non-conservative collisions.
