L2−L3XCoster-Kronig Transition Probability atZ=82

Abstract
The probability for Coster-Kronig transfer of vacancies from the L2 to the L3 subshell of Pb is measured by observing the K x-ray spectrum in coincidence with Lα x rays in the electron-capture decay of Bi207. The intensity of the Kα2 component of the coincident spectrum is a measure of the L2L3X Coster-Kronig transition probability. A value of 0.156 ± 0.010 is obtained for f23.
