✦ Synopsis

A derivation is given of an effective Hamiltonian to be used in treating the decay of atomic states perturbed by a static applied field. This Hamiltonian is an improvement on that usually used in writing Bethe-Lamb equations. It includes the virtues of a Stark-perturbed golden rule method which has recently proved successful in treating decays of metastable states in helium, where the usual Bethe-Lamb approach fails.
