Hydrogen atoms perturbed by some periodic impulsive electric fields

Abstract

Calculations on a classical hydrogen atom, perturbed by equal and equally spaced electric field impulses, are compared with analogous quantal calculations performed by Dhar et al. (1983). The classical and quantal ionisation probabilities are of the same order of magnitude. Classical stochasticity is observed. Then calculations on a classical hydrogen atom, perturbed by alternating electric field impulses, are compared with calculations performed by Leopold, Percival and Jones et al. (1980), on a hydrogen atom perturbed by a microwave field. The two systems exhibit similar mechanisms of ionisation.
