Atom Collision

Electron–hydrogen collision in the presence of a circularly polarized laser field is studied within a formalism based in an appropriate space-translations transformation and the Green's function formalism. The Born–Oppenheimer approximation for the scattering amplitude is obtained and the dependence of the differential and total excitation cross section on the electromagnetic field polarization is studied.

Heisenberg Representation

The method of the 1934 theory of Dirac and Heisenberg is discussed and exemplified by treating the case of an external electromagnetic field. Polarization tensors are introduced which, while showing clearly the features of the well-known divergent expressions of recent calculations, are throughout well-defined in the mathematical sense. The current operator in the Heisenberg representation is calculated in the power series expansion, and the com­pensation of singularities in the vacuum-to-vacuum transition amplitude is indicated.
