Angular distribution of Auger electrons and photons in resonant transfer and excitation in collisions of ions with light targets.

Abstract

It is shown that angular distributions of Auger electrons and x rays from deexcitation of doubly excited states produced in the resonant transfer and excitation of projectiles in collisions with light targets are, in general, not isotropic. The detailed theoretical results for the 2${\mathit{p}}^{2}$ $^{1}\mathrm{D}$ resonance in ${\mathrm{F}}^{8+}$+e/r${\mathit{H}}_{2}$ are presented at a projectile energy of 20 MeV.
