Abstract

Photodetachment of [Formula: see text] near a soft reflecting surface is investigated by using theoretical imaging method. Analytical expressions are derived for detached electron flux and photodetachment cross section. The surface strongly affects the results and induces oscillation in the detached electron spectra. The photodetachment cross section is double of the H- near a plane wall. For a very large distance between the surface and [Formula: see text](R → ∞) the cross section reduces to the cross section of two center system in free space.
