The electron-stimulated ${\mathrm{O}}^{\mathrm{\ensuremath{-}}}$ desorption yields from ${\mathrm{O}}_{2}$ condensed on a thick rare-gas (Ar, Kr, or Xe) film are reported. It is shown that coherent scattering of electrons in the rare-gas film dramatically enhances the ${\mathrm{O}}^{\mathrm{\ensuremath{-}}}$ yields near the Bragg reflection energies.
