Dielectronic recombination of Pb79+ via high angular momenta

Abstract

We have used the AUTOSTRUCTURE code to carry out semirelativistic calculations for the dielectronic recombination of Pb79+ via the 2s1/2−2p1/2 core excitation. We obtain excellent agreement between these semirelativistic results and measurements made at Gesellschaft für Schwerionenforschung, in particular, for the high angular momentum peak of the 2p1/220lj resonances. The factor of 3 underestimate in the result for this peak that was originally obtained by Mitnik et al., which has led some to conclude that only a fully relativistic approach can describe dielectronic recombination via high angular momenta in very heavy highly charged ions, are found to be in error.
