DECAY OF Ce$sup 144$ AND Pr$sup 14$$sup 4$
The beta and gamma spectra from the decay of Ce/sup 144/ and beta spectrometer and single-channel scintillation spectrometers. Three partial beta spectra with end-point energies and relative intensities of 184 kev (30%), 245 kev (5%), and 320 kev (65%) were observed for Ce/sup 144/. Gamma rays and internal conversion lines corresponding to 54, 80, and 134-kev transitions were also detected. Internal conversion coefficients indicate an M1 multipolarity for the 80- and 134-kev transitions. Pr/sup 144/ yields three partial beta spectra with end-point energies and relative intensities of 0.90 Mev (2%), 2.45 Mev (3%), and 3.15 Mev (95%). Corresponding gamma rays were also detected. Beta-gamma and gamma-gamma coincidence measurements substantiate the proposed decay scheme. (auth)
