The energies and intensities of 10 transitions in IS5Re following the decay of 1s50s have been determined using Ge(Li) detectors and a magnetic beta-ray spectrometer. Internal conversion measurements made at a resolution of 0.15% in momentum have yielded the n~ultipole character of the 9 strongest transitions. The proposed decay scheme has been tested by a two parameter y-y coincidence experiment.The decay energy has been found to be 1012 2 3 keV from y-X coincidence measurements involving the 646, 717, 875 f 880, and 931 keV transitions.
