By the use of two proportional counters in coincidence and with vacuum- evaporated sources of less than 0.5 mu g/cm/sup 2/, the photon and conversion electron spectrum of the 8.4-kev level of Tm/sup 169/, produced by the decay of Er/sup 169/ was studied. The branching ratio io the excited level of Tm/sup 169/ was determined as (42 plus or minus 1)%. The internal conversion coefficient was found to be alpha /sub M/ + alpha /sub N/ = 106 plus or minus 6. (tr-auth)
