Sb/sup 115/ (32 min) decays by electron capture and positron emission to Sn/sup 115/, the positron branch accounting for (12 plus or minus 3)% of the disintegrations. Of the total disintegrations 94% lead directly to a previously known 490-kev level in Sn/sup 115/. The remaining 6% of the disintegrations are to an excited state in Sn/sup 115/ and are followed by two gamma rays in cascade whose energies are 980 and 1240 kev, respectively. The crossover gamma ray of 2220 kev is also seen, with an intensity equivalent to 1% of the disintegrations. The cascade and crossover gamma rays lead to the 499kev level and coincidences were observed between these gamma rays. An upper limit of 0.4% was obtained for a beta branch from In/sup 115m/to the 499-kev level in Sn/sup 115/. These levels in Sn/sup 115/ seem to be too high in energy to correspond to the predicted low- lying levels. (auth)
