Description

The level structure of 149 Pm has been investigated by studying the gamma rays emitted following the beta decay of 149 Nd (T1/2 =1.7 h). The single and the gamma-gamma coincidence spectra were taken using several HPGe detectors with high energy resolution. The energy and relative intensities of 181 gamma rays have been determined with a better overall precision than previously. A decay scheme with 51 levels have been proposed . This include 6 new levels at: 1407 keV, 1368 keV, 1364 keV, 1329 keV, 1293 keV and 1181 keV . The present results, together the results of earlier studies, permitted assignments of spin and parity for a number of these levels. (author)
