Abstract
A nuclear spectroscopic study of the high-spin ground state of () showed substantial differences from earlier work. The sources, prepared by the and reactions, were chemically separated and purified. A total of 34 rays (139.9-1167.1 keV) were observed of which 13 are new; nine others which were reported previously are not confirmed. Absolute intensities of the rays were determined with the aid of beta measurements. A modified decay scheme is proposed and discussed; six levels in with are assigned to a octupole vibrational band. The half-life measured with high purity sources is 61.9±0.2 min.
