Abstract
A fast-slow coincidence spectrometer was used to study the decay of . A 650-kev gamma ray found in the single-channel spectrum was shown to be in coincidence with the x ray both in the fast and in the slow coincidence spectra. This confirmed the existence of a 650-kev level in fed by a weak orbital capture branching. From the relative intensities of the 257-kev gamma rays and the 650-kev gamma rays (16.4±1.9:1), it was determined that the spin of the 650-kev level is and the parity is odd. The absence of positrons and arguments from classifications indicate a spin of and even parity for the ground level of and a decay energy in the range of 0.8 to 1.6 Mev. The shape of the corrected inner brems-strahlung spectrum indicated a decay energy of 1.3±0.3 Mev.
