Abstract
Average - and -shell-vacancy distributions produced in the deexcitation of atoms that have been singly ionized in the shell or one of the 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 coupling from nonrelativistic screened hydrogenic wave functions of the following radiationless transition rates: , , and for selected elements with , and , , and for . Experimental and theoretical data on Auger- and radiative-transition probabilities are critically compared. Auger-electron intensity ratios and and 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 vacancy, of vacancy production in each subshell is derived from experimental data and tabulated for ; 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 -shell-vacancy production in the decay of and vacancies is derived from theory and tabulated for selected atoms with .
