Abstract MeanL-shell x-ray fluorescence yields $$(\bar \omega _L )$$ have been measured by observingK andL x-ray spectra emitted in the decay of109Cd,145Pm, and153Gd with a high resolution Si(Li) x-ray detector. The results forZ=47, 60, and 63 are as follows: $$\bar \omega _L $$ =0.0425±0.0064, 0.131±0.017, and 0.142±0.023, respectively. Additional values of $$\bar \omega _L $$ from this laboratory atZ=55, 56, 57, 59, and 65 are also tabulated as are previous experimental values atZ=47, 60, and 63. For comparison, theoretical estimates of $$\bar \omega _L $$ were computed using theoreticalL-subshell fluorescence and Coster-Kronig yields, together with subshell vacancy distributions calculated from the literature. The theoretical estimates atZ=47, 60, and 63, based on the subshell calculations of Chen, Crasemann, and Kostroun, agree well with experiment.
