英文摘要: We study the photodetachment cross sections of H(-) near a metal surface using closed-orbit theory. Formulas for cross sections are presented. We find the metal surface mainly modifies the photodetachment cross sections near threshold. It induces a strong oscillation in the photodetachment cross section between threshold and an energy 1/4d above threshold, where d is the distance between the negative ion and the metal surface. Below threshold the photodetachment cross section near a metal becomes finite because of quantum tunneling effect. The oscillation in the cross section is identified with a closed orbit and explained as an interference of the detached electron.
