Abstract
The radiations from have been examined by means of a thin lens spectrometer and absorption-coincidence techniques. The half-life was found to be 33±1.5 days. The half-life of the metastable state was determined as 0.67 μ sec. decays by electron-capture to . Eleven gamma-rays were observed in the photoelectron and internal conversion spectra determined with the spectrometer. On the basis of the absorption-coincidence and spectrometer data, two decay schemes are discussed.
