Widths and fluorescence yields of atomicL-shell vacancy states

Abstract

A comprehensive set of theoretical $L$-shell Auger and total widths, and Coster-Kronig and fluorescence yields is presented for atomic numbers $18\le Z\le 100$. These quantities are based on ab initio relativistic calculations. Agreement with experimental values is fair for ${\omega }_1$ and generally good for ${\omega }_2$, ${\omega }_3 (Z\ge 54)$, $f_{23} (Z\ge 60)$, $\Gamma \left(L_2\right)$, $\Gamma \left(L_3\right)$, and for $\Gamma \left(L_1\right)$ in the range $49\le Z\le 75$. Discrepancies in $\Gamma \left(L_1\right)$ for $Z<\mathrm{}49\mathrm{}$ point toward the need for a many-body calculation of low-energy $L_1-L_{2,3}{M}_{4,5}$ Coster-Kronig transitions. There is a pronounced need for measurements of ${\omega }_3$ and $f_{23}$ of elements lighter than Xe.
