Asymptotic distorted-wave approximation for electron-molecule scattering

Abstract

An asymptotic distorted-wave method is proposed for electron-molecule scattering calculations, designed to bridge the gap between accurate variational calculations, feasible only for low partial-wave l values, and partial-wave Born calculations, valid for large l. Calculations of K matrices in the 2 Sigma u+ scattering state of e -+H2 illustrate the method.
