Abstract: We describe a method for calculating rates for multiphoton detachment or ionization of a two-electron system by a perturbative field. We have applied the method to ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$, and we present estimates of two- and three-photon detachment rates. In particular, we explore the $^{1}$${\mathit{S}}^{\mathit{e}}$ and $^{1}$${\mathit{D}}^{\mathit{e}}$ Feshbach resonances below the n=2 and n=3 excitation thresholds of H; these resonances lie in the ``excess-photon detachment'' regime, where one photon is already sufficient to detach the electron.
