The total Coster-Kronig transition probability f/sub 23/ for the L/sub 2/-L/sub 3/ transition and the L/sub 2/ and L/sub 3/ subshell x-ray fluorescence yields ..omega../sub 2/ and ..omega../sub 3/ were measured utilizing resolved L-K x-ray coincidence techniques for Z=64 and 67 with radioactive sources of 4.68-yr /sup 155/Eu and 10.4-h /sup 165/Er, respectively. Improved accuracy in the results is achieved by advances in the experimental method. The values of f/sub 23/ are 0.130 +- 0.012 and 0.115 +- 0.011 at Z=64 and 67, respectively, and of ..omega../sub 2/ and ..omega../sub 3/ are 0.165 +- 0.022 and 0.161 +- 0.019 at Z=64, and 0.186 +- 0.023 and 0.180 +- 0.020 at Z=67, respectively. The quoted uncertainties are twice the average deviation from the mean of 12 values of f/sub 23/ and two values each of ..omega../sub 2/ and ..omega../sub 3/, and arise predominantly from systematic errors.
