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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
