Photodetachment of H$^{-}$ near a partial reflecting surface

TL;DR

This paper presents a theoretical study of how a partial reflecting surface affects the photodetachment of H$^{-}$, analyzing absorption effects on cross sections using a new reflection parameter to quantify surface reflection.

Contribution

It introduces a reflection parameter K to model the surface's absorption effect on detached-electron waves, providing a new approach to interpret photodetachment near surfaces.

Findings

Absorption effects significantly alter total and differential cross sections.

The reflection parameter K effectively quantifies surface reflection impact.

Theoretical insights aid understanding of electron-surface interactions.

Abstract

Theoretical and interpretative study on the subject of photodetachment of H$^{-}$ near a partial reflecting surface is presented, and the absorption effect of the surface is investigated on the total and differential cross sections using a theoretical imaging method. To understand the absorption effect, a reflection parameter $K$ is introduced as a multiplicative factor to the outgoing detached-electron wave of H$^-$ propagating toward the wall. The reflection parameter measures, how much electron wave would reflect from the surface; K=0 corresponds to no reflection and K=1 corresponds to the total reflection.
