KAuger rates calculated forNe+

Abstract

Starting with a $1s$ vacancy in the neon atom, Auger rates are calculated for transitions to the final $\mathrm{LS}$-coupled states of ${\mathrm{Ne}}^{++}$. Electron correlations are found to have a significant effect on these rates. Although the configuration mixing of ${\mathrm{Ne}}^{++}$ ${\mathrm{}\left(1s\right)\mathrm{}}^2{\mathrm{}\left(2s\right)\mathrm{}}^2{\mathrm{}\left(2p\right)\mathrm{}}^4 {}_{}{}^1{}_{}{}^{}S$ and ${\mathrm{}\left(1s\right)\mathrm{}}^2{\mathrm{}\left(2p\right)\mathrm{}}^6 {}_{}{}^1{}_{}{}^{}S$ is important, good results are only obtained by also considering the other correlation effects representing mixing with other configurations. The ratios of calculated Auger rates relative to the $1s-2s2s {}_{}{}^1{}_{}{}^{}S$ rate are in close agreement with experiment. However, the calculated absolute rates are all higher than the experimental values of Mehlhorn, Stalherm, and Verbeek by factors ranging from 1.4 to 1.5.
