A simple model, accounting for multiple-hole configurations, is presented in order to study the relative intensities of observed satellite and diagram x-ray lines following L-shell ionization in the region around Z = 50. Since satellites arising from LN double- and LNN triple-hole states generally are embedded within the natural width of the parent diagram lines and the observed satellites are due to LM and/or LMX (X = M,N) multiple-hole states, a clear distinction is drawn among the different multivacancy distributions. Moreover, Coster-Kronig transitions and shakeoff processes, which are responsible for the observed satellite structures, are explicitly taken into account. A new analysis of the L-series x-ray spectra, induced by 2.5-MeV proton bombardment, for elements Z = 47--53 has been performed based on the present model. L/sub 1/-subshell level widths GAMMA/sub 1/, fluorescence yields ..omega../sub 1/, partial Coster-Kronig transition rates f/sub 13//sub M/, and shakeoff probabilities P/sub M/ have been obtained. Present values are in good agreement with recent measurements. However, they show large disagreement with both theoretical calculations and compiled data due to the overestimated intensity and to the assumed sharp cutoff of the L/sub 1/-L/sub 3/M/sub 4,5/ Coster-Kronig transition rates.
