Abstract
The level scheme of Pr/sup 144/ following beta -decay of Ce/sup 144/ was studied with a Siegbahn-Slatis beta -ray spectrometer and scintillation spectrometers. Three beta -groups were observed with end-point energies and relative intensities as gamma-rays of energies 53, 81, and 134 kev were detected. Internal conversion lines of these transitions along with those of some other gamma -lines of energies 33, 38, 42, 59, and 95 kev were observed. K/L ratio and half-time measurement of the 134 kev gamma -line indicate an Ml multipolarity for this transition. Coincidence studies were made and a tentative decay scheme proposed (auth)
