Positron Collision Dynamics for C2–C3 Hydrocarbons

Abstract

This article presents positron scattering cross sections for simple hydrocarbons, viz., ethane, ethene, ethyne, propane, and propyne. The present work focuses on the calculation of different elastic and inelastic interactions due to positron impact with simple hydrocarbons in terms of inelastic cross sections (both with and without positronium formation channel), electronic excitation cross section (Qexc) and momentum transfer cross section (Qmtcs). Knowing that positron-plasma study is one of the trending fields, the calculated data have diverse plasma and astrophysical modeling applications. Due to the lack of previous studies, all the cross sections presented have been reported for the first time.
