Auger and radiative deexcitation of multiply ionized Ne

Abstract

Radiative and Auger transition probabilities to the $1s$ state have been calculated for the individual multiplets of $\mathrm{Ne}{\mathrm{}\left(1s\right)\mathrm{}}^1{\mathrm{}\left(2s\right)\mathrm{}}^j{\mathrm{}\left(2p\right)\mathrm{}}^k$ configurations. From multiplet fluorescence yields, the effective fluorescence yields ${\overline{\omega }}^i$ for Ne $K{L}^i$ charge states were derived. For statistical distribution of multiplet states, we find ${\overline{\omega }}^i=0.0159, 0.0176, 0.0199, 0.0248, 0.0390, 0.0862, \mathrm{and} 0.229$ for $i=0, \dots , 6$. These theoretical fluorescence yields agree well with experimental results from collisions of 30-MeV ${\mathrm{O}}^{5+}$ ions with Ne.
