The value of the L/sub 2/-L/sub 3/ Coster-Kronig transition probability (f/sub 23/) in Pb has been determined by multiparameter K versus L x-ray coincidence measurements using high-energy-resolution germanium and silicon detectors. The Pb x rays were obtained from a radioactive source of /sup 207/Bi. A new method of data analysis to determine the contribution of K..cap alpha../sub 1/ x rays to the K..cap alpha../sub 2/ x-ray peak is described. Precise determination of this contribution is crucial to accurate measurement of f/sub 23/. The value obtained, f/sub 23/ = 0.112 +- 0.001, is slightly lower than predicted by the latest theoretical calculations. A trend toward deviations from theory in the same direction appears to be confirmed by recently measured values of f/sub 23/ in other medium- and high-Z atoms.
