Oscillations of electron flux in photodetachment of H- in an electric field.

Abstract

Outgoing electron waves produced in the photodetachment of ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ are propagated to large distances in a homogeneous electric field, and the electron flux is then computed. It is shown that the interference of waves propagating along two distinctive paths from the region of the bound state of ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ to the same point induces oscillations in the electron flux distribution. Simple analytic expressions are presented for the flux distribution.
