摘要：

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 H-, and we present estimates of two- and three-photon detachment rates. In particular, we explore the 1S(e) and 1D(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.
