Amplitude-distortion factors for the inelastic scattering of an electron at a neon atom in an electric field

Abstract

Inelastic electron scattering at a neon atom in the presence of an external electric field is considered. The distortion factors of the cross sectionη γM (F) are calculated for a series of 4d and 5d levels. It is shown that the distortion factor in strong fields is a nonlinear and nonmonotonic function of the field. The distortion factors and transition probabilitiesA γγ′ , are compared. The correlation between the behavior ofA γγ′ , andη γM (F) is explained by the dependence of the mean dipole moment of the Stark state on the field strength.
