Abstract
Beta-decay spectroscopy of the ground state was performed at the KEK Isotope Separation System. -delayed rays corresponding to the previously reported in-beam transitions were observed. The -decay half-life of the ground state was determined to be 283(10) s by analyzing a time spectrum of coincidence events. The -decay branching ratio and log() values were evaluated for the first time. Based on the newly evaluated log() values of and a decay scheme, spin-parity values of originating from the odd-proton orbit were assigned with high confidence, which is consistent with the systematics of neighboring odd- nuclides.
