The present status of the field of fluorescence yields, radiationless (Auger and Coster-Kronig) and radiative transition probabilities is summarized. Tables of experimental and theoretical results are included, and tables of "best values" of important quantities are presented.

X-Ray Fluorescence Yields, Auger, and Coster-Kronig Transition Probabilities

Fluorescence yields and Coster–Kronig probabilities for the atomic L subshells

Average $L$- and $M$-shell-vacancy distributions produced in the deexcitation of atoms that have been singly ionized in the $K$ shell or one of the $L$ subshells are derived from a comprehensive set of available experimental and theoretical data on radiative- and Auger-transition rates. The data are supplemented by new calculations in $j\ensuremath{-}j$ coupling from nonrelativistic screened hydrogenic wave functions of the following radiationless transition rates: $K\ensuremath{-}LL$, $K\ensuremath{-}LM$, and $K\ensuremath{-}LN$ for selected elements with $20\ensuremath{\le}Z\ensuremath{\le}81$, and ${L}_{i}\ensuremath{-}MM$, ${L}_{i}\ensuremath{-}MX$, and ${L}_{i}\ensuremath{-}XY$ for $26\ensuremath{\le}Z\ensuremath{\le}93$. Experimental and theoretical data on Auger- and radiative-transition probabilities are critically compared. Auger-electron intensity ratios and $\frac{K{\ensuremath{\alpha}}_{2}}{K{\ensuremath{\alpha}}_{1}}$ and $\frac{K\ensuremath{\beta}}{K\ensuremath{\alpha}}$ x-ray intensity ratios from a best fit to experimental data are tabulated for even atomic numbers from 20 to 94. The probability, per initial $K$ vacancy, of vacancy production in each ${L}_{i}$ subshell is derived from experimental data and tabulated for $20\ensuremath{\le}Z\ensuremath{\le}94$; components due to Auger and x-ray transitions are listed separately. These probabilities agree well with purely theoretical vacancy distributions also derived here. The probability of $M$-shell-vacancy production in the decay of $K$ and ${L}_{i}$ vacancies is derived from theory and tabulated for selected atoms with $16\ensuremath{\le}Z\ensuremath{\le}93$.

Activation cross sections at an incident neutron energy of 14.4\ifmmode\pm\else\textpm\fi{}0.3 MeV are measured for the ($n,2n$), ($n,p$), and ($n,\ensuremath{\alpha}$) reactions on isotopes of As, Br, Rb, and Sr, by using the mixed-powder method and $\ensuremath{\gamma}$ detection by Ge(Li) spectrometer. The use of a stoichiometric chemical compound as an alternative to the mixed-powder technique, where one of the constituents serves as the neutron flux monitor, is investigated and is recommended, whenever applicable, over all other methods for measurement of relative activation cross sections.
