• Energies and relative intensities of gamma transitions following the decay of "'Pm were measured with Ge(Li) detectors and 94 gamma rays were observed.The half-life of "'Pm was determined to be 16[.9i0.9 min. Gamma-gammacoincidence and gamma-gamma anticoincidence measurements were performed.From these measurements the ]670keV,2371 keVand2700keVlevelsareproposedamtd the 2679 keV level is excluded. From beta-gamma coincidence measurementsthe beta-ray feeding to the ground state was found. By using a !2n beta-rayspectrometer, the beta-ray maximum energy of the transition to the first excitedstate was determined to be 3120+20 keV and the intensity ratio of the ground-state transition to this transition was 0.085880.0043. From gamma-gammaangular correlation measurements E2/Ml or M2/El mixing ratios of severalgamma rays were obtained.
