Abstract

Gamma-ray emission probabilities for W-187 have been determined with uncertainties less than 1% from measurement of absolute gamma-ray intensities and disintegration rate. The measured emission probabilities are larger than those previously reported by about 20% and hence the beta-ray branching ratio to the ground state has to be smaller than about 40%. The decay scheme of W-187 calculated by using the present results is given as a final result.
