A model of strong bound-free coupling by a stochastic train of delta-function impulses is solved analytically. The model can be used to describe transitions caused by strong isolated collisions. The decay of bound-state population and photoelectron spectra is discussed, and the limits of the applicability of Fermi’s Golden Rule are evaluated. It turns out that the results depend nontrivially on the statistics of the driving signal.
