摘　　要：We describe the effects of plane surface on the photo-detached electron spectra from H^(-)_(2).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 H^(-)_(2) from the surface and also on the separation of atomic centers of H^(-)_(2).The results show strong oscillations for smaller values of distances,whereas for larger values the oscillating structure disappears.
