Examinations of KLL capture of electrons into highly charged heavy ions — •Z. Harman, S. Zakowicz, N. Grün und W. Scheid — Institut für Theoretische Physik der Justus-Liebig-Universität Gießen

Relativistic calculations for RTE processes (Resonant Transfer and Excitation) are presented for the collisions of hydrogen-like uranium ions with hydrogen atoms in the energy range of the KLL resonances. First the cross sections for dielectronic recombination (DR) are obtained perturbatively within the isolated resonances approximation. The RTE cross sections are given by a folding of the DR cross sectios with the Compton profile of the target atoms. The influence of higher order terms of the electron-electron interaction going beyond the Breit interaction will be discussed. The possible effects originating from the emission of more than one photon will also be covered.
