Abstract We describe the effects of plane surface on the photo-detached electron spectra from H2−. A z−polarized laser is used for the detachment of electrons. The detached electron flux and photodetachment cross section are derived. There exists strong dependence on the distance of the H2- from the surface and also on the separation of atomic centers of H2−. The results show strong oscillations for smaller values of distances, whereas for larger values the oscillating structure disappears.
