Atomic Fluorescence Yields

The mechanisms of the reorganization of atoms with inner shell vacancies are reviewed. All available experimental values of $K$-, $L$-, and $M$-shell fluorescence yields, together with $L$-shell Coster-Kronig yields are summarized and compared with available theoretical calculations. Rather good agreement exists in general between theory and experiment for the $K$ shell, but experimental values of the $L_2$ and $L_3$ subshell fluorescence yields disagree substantially with the semitheoretical results of Listengarten. Related phenomena in $\mu$-mesic atoms are included. Experimental methods of measurement are summarized and discussed, together with suggestions for future studies with high resolution techniques. Results from the literature have been included up to 10 May 1966.
