摘要：
Photodetachment of H-2(-) near a soft reflecting surface is investigated by using theoretical imaging method. Analytical expressions are derived for detached electron flux and photo-detachment 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 H-2(-) (R -> infinity) the cross section reduces to the cross section of two center system in free space.
