Abstract

Precision energy measurements on 8 gamma rays in the 147Nd→ 147Pm decay were made with a 2m curved-crystal spectrometer. Energies of the 6 other gamma rays were determined with a Ge(Li) spectrometer. The relative intensities of all gamma rays were determined. A level scheme is proposed for 147Pm which includes a new level at 680.4 keV. Evidence is given to support the exclusion of several levels reported by earlier investigators. Results are compared with predictions of intermediate coupling theory.
