Calculation of differential cross section for dielectronic recombination with two-electron uranium

Abstract

Calculation of the differential cross section for the dielectronic recombination with two-electron uranium within the framework of QED is presented. The polarization of the emitted photon is investigated. The contributions of the Breit interaction and the interference of the photon multipoles are studied.

Energy Levels of Core-Excited 1s2l2l′ States in Lithium-Like Ions: Argon to Uranium

“…Finally, Table V compares our results for Li-like uranium with a recent calculation by Lyashchenko and Andreev [32]. We observe a systematical shift of energies ranging from 6 eV to 13 eV.…”

“…We note that our results for the 1s 2 2s energies are cross-checked by comparing two different methods (see Table I), so the deviation is most likely to be due to insufficiently accurate treatment of QED screening effects in Ref. [32].…”
