Abstract
The decay of has been studied with the aid of a thin magnetic lens beta-ray spectrometer and coincident scintillation spectrometers. Two principal beta-ray groups, with the end-point energies 580±10 and 940±15 kev have been observed to decay with the 18-hour half-life of , revealing energy levels in the residual nucleus, , at 56, 136, and 361 kev. The coincidence measurements gave evidence of a third beta component, with the end-point energy of 880±20 kev, coincident with the 56-kev gamma ray. The intensities of the three components (580±10, 880±20, and 940±15 kev) have been estimated to be approximately 20, 6, and 74%, respectively. Internal conversion coefficient measurements indicated the 361-kev gamma ray to be a mixed ( and ) transition.
