Quantum-Mechanical Theory of Elastic Scattering and Cross Section Determination of Particle Interactions in Plasma

Abstract

A quantum-mechanical description of the theory of elastic scattering and a technique for determining the cross sections of particle interactions in plasma are described. An asymptotic solution of the Schrödinger equation for the elastic interaction of plasma particles is presented. Algorithms for determining phase shifts based on the Modified Effective Range Theory (MERT) are given. The Born approximation is considered to determine the amplitude of the scattered waves and the scattering cross section of the particles. Data are presented on the cross sections for scattering of electrons by atoms and ions in argon.
