Abstract
The decay properties of were investigated with the use of mass-separated sources. Singles and coincidence measurements were made by using x- and -ray Ge(Li) detectors as well as a Si(Li) electron detector. These results were combined with previously available conversion-electron data which had been obtained with a magnetic spectrometer. From this information a level scheme was constructed for . A tentatively proposed level at 317 keV was eliminated on the basis of our results. In addition, several transitions attributed to decay were not observed in the present study. particle and -ray spectra were also measured with the detectors positioned in calibrated geometries. The -decay energy and branching ratio of were determined to be 3915±10 keV and (2.8±0.5)×, respectively.
