Ionization energies of hydrogenlike atoms in intense electromagnetic fields
An analytic expression is derived for the energy spectrum of hydrogenlike atoms in an intense radiation field, which is valid up to intensities for which R0a Bohr radius, where R0 is the amplitude of the classical displacement of a free electron in the radiation field. © 1975 The American Physical Society.
