Decay scheme of Pr144

Abstract

The decay of the 17.5 ruin Pr l~a has been investigated with a scintillation speetrometer. The energy of the gamma transitions in the daughter nucleus Nd 1~ ate found to be 2.18, 1.49 and 0.70 MeV in agreement with the measurements of other investigators. The ambiguities concerning the previous]y reported 2.8, 1.67 and 1.16 MeV gamma transitions ate removed. A decay seheme is then proposed.
