Mechanistic investigation of vibrational fine structure in e-H-2 scattering using local complex potential-based time dependent wave packet approach

Abstract

The structural features of vibrational excitation cross-sections in resonant e-H-2 scattering have been investigated using a time dependent wave packet approach and a local complex potential to describe the (2)Sigma(+)(u) H-2(-) anion. An analysis of the partial contributions to the vibrational excitation cross-sections reveals that all features of the excitation profile result from simple interference between bound vibrational levels of H-2 and H-2(-).
