Abstract
We present a soluble model of an atomic system driven by a train of δ-function impulses. The atomic Hamiltonian describes an atom with one bound state and one continuum representing an autoionizing resonance. The model is soluble or requires very simple numerics. The results depend strongly on the shape of the resonance. Population trapping is discovered for a Gaussian-shaped continuum. Corrections coming from the counterrotating terms are discussed.Keywords
