| 摘 要： | The photo-detachment cross section of H^- near two parallel elastic interfaces is derived and calculated by using the closed orbit theory. The photo-detachment cross section of H^- near two interfaces is shown to exhibit multi-periodic oscillations when the distance between the H^- and the interface is varied. Each peak in the Fourier transformed photo-detachment cross section corresponds to the length of a closed orbit, which is quite similar to the case of atomic spontaneous emissions in a dielectric slab. This study provides a new understanding of the photo=detachment process of H^- in the presence of interfaces.

| Abstract: | The photo-detachment cross section of H- near two parallel elastic
interfaces is derived and calculated by using the closed orbit theory. The
photo-detachment cross section of H- near two interfaces is shown to
exhibit multi-periodic oscillations when the distance between the H-
and the interface is varied. Each peak in the Fourier transformed
photo-detachment cross section corresponds to the length of a closed orbit,
which is quite similar to the case of atomic spontaneous emissions in a
dielectric slab. This study provides a new understanding of the
photo-detachment process of H- in the presence of interfaces. |
