Sudden-perturbation approximation for the dirac equation

M. V. Lomonosov Pomor State University

Abstract: We solve the Dirac equation describing the behavior of a hydrogen-like atom interacting with a spatially inhomogeneous ultrashort electromagnetic field pulse in the sudden-perturbation approximation. We express the corresponding transition probabilities through the known inelastic atomic form factors widely used in the theory of relativistic collisions of charged particles with atoms.

Keywords: atom, ultrashort electromagnetic field pulse, sudden-perturbation approximation, Dirac equation.
