IONIZATION MULTIPLICATION - M-SHELL VACANCIES RESULTING FROM AN INITIAL LI-SUBSHELL VACANCY AT Z=83

The quantities nLiM, the number of M-shell vacancies resulting from an initial Li-subshell vacancy, have been determined by combining information from the L-Auger-electron intensity measurements of Haynes et al. with the L x-ray intensities of Freund and Fink. The values found are nL1M=1.77, nL2M=1.44, and nL3M=1.36, to within 10% accuracy. © 1969 The American Physical Society.
