Metastable states in the antiprotonic helium atom decaying via Auger transitions - art. no. 062501

摘要

In the present paper, we perform a systematic calculation of the complex resonance energy for metastable states in the antiprotonic helium atoms, which decay predominantly via Auger transitions, by using the complex-coordinate rotation (CCR) method. Special attention is paid to relativistic corrections for the bound electron related to the Breit interaction. These corrections have been calculated using the CCR wave functions, which are square integrable. Some higher-order relativistic and QED effects have been included into consideration to get precise theoretical values for transition frequencies. [References: 29]
