The K-conversion coefficient of the 279-kev transition in Tl/sup 203/ was measured by a coincidence technique. The Kconversion electrons and beta rays following the decay of Hg/sup 203/ were detected in a magnetic lens spectrometer in coincidence with x rays and gamma rays, respectively. From these data, the probability of K-conversion electron emission kappa /sub eK/ was determined to be 0.132 plus or minus 0.002. The Kconversion coefficient was calculated from epsilon /sub K/ = kappa /sub eK//STA1- kappa /sub e K/ (K + L + M + N)/K! to be 0.162 plus or minus 0.003. The consistent epsilon /sub K/ results from several different techniques suggest this is a useful standard for conversion coefficient measurements in this energy range. (auth)
