Correspondence Between Quantum and Classical Dynamics in Photodetachment Near Elastic Wall

摘要

The photodetachment of H~-near an elastic wall was investigated and an analytical formula of the cross section was derived. It was found that the cross section is a superposition of a smooth background and sinusoidal oscillation,which depends on the distance between the ion and the elastic wall. The classical dynamics of the photo-detached electron and its quantum correspondence was analyzed. In this model,the semiclassical photodetachment cross section is exactly the same as the quantum result.
