Self-consistent description for x-ray, Auger electron, and nuclear excitation by electron transition processes

Abstract

The physical processes about x-ray emission, Auger electron emission, and nuclear excitation by electron transition (NEET) induced by deexcitations of the excited atomic states, e.g., the inner shell hole states, are studied self-consistently in the unified nonrelativistic quantum mechanics framework. The emphasis is on exploring the NEET process and its interference with the other two processes. The transition probabilities of these deexcitation channels are given in analytical forms. The numerical calculations for $_{76}^{189}\mathrm{Os}$, $_{79}^{197}\mathrm{Au}$, and $_{93}^{237}\mathrm{Np}$ have been done and compared with the available experimental results.
