Abstract
Permanent magnet electron spectrographs, a double-focusing electron spectrometer, and gamma-scintillation spectrometers have been used to measure the energies and intensities of radiations which accompany the decay of . From these data, the conversion coefficients, multipolarities, and mixing ratios of a number of the transitions have been determined. Some new transitions are reported, and a revised level scheme, incorporating all but one of the observed transitions, is proposed for . A half-life of 10.87±0.12 h has been determined for . The gamma-scintillation spectrum obtained from a pure source of is reported. The half-life of which has been measured is 13.3±0.1 days.
