On the anisotropy ofδ-electrons from slow heavy-ion collisions in the emission angles ϑf andϕ f

Abstract

Within the united-atom perturbation theory, we have calculated the probability for the ejection of electrons from theK andL shells of heavy target atoms as a function of both polar and azimuthal angle of the electron. By including multipole transitions up tol=2, we found that for asymmetric collision systems and high electron energies the angular distribution has a dipole shape. Fors 1/2 electrons, the dependence on the azimuthal angle varies strongly with impact parameterb, with a preference of electron ejection in the same direction as the scattered projectile for smallb, and in the opposite direction for largeb. This is in agreement with first experimental data.
