Radiations ofXe127

Abstract

The radiations of ${\mathrm{Xe}}^{127}$ have been examined. The energies of previously observed gamma rays were found to be 58±1, 146±0.5, 173.0±0.5, 204.5±0.5, and 377.5±0.5 kev. Conversion electron intensities relative to gamma-ray intensities and internal conversion coefficients were measured. The experiment indicates that electron capture to the ground state is suppressed. Spin and parity assignments are proposed for the 204- and 377-kev excited states of ${\mathrm{I}}^{127}$.
