Abstract
The photodetachment of H - ions in a nonuniform electric field has been investigated on the basis of closed orbit theory .We put forward an analytical formula for calculating the photode-tachment cross section of this system .Our study suggests besides the closed orbit previously re-ported for the photodetachment of H - in a uniform electric field ,some additional closed orbits are produced owing to the effect of the nonuniform electric field .Compared with the photodetach-ment cross section of H - in a uniform electric field ,the oscillation in the cross section of my sys-tem becomes much more complicated and the cross section exhibits a multiperiodic oscillatory structure .To show the relationship between the oscillation in the photodetachment cross section and the detached electron’s classical closed orbits clearly ,we make a Fourier transformation for the scaled photodetachment cross section of this system .Each peak in the Fourier transformed cross section corresponds to the contribution of one closed orbit .This study provides a new un-derstanding of the photodetachment of negative ions in the presence of a nonuiform electric field .关键词
