The decay of 12.4 y 152Eu to 152Sm and 152Gd was studied in a high resolution singles measurement and two 4096 • 2048 Ge(Li)--Ge(Li) coincidence studies. Fortyfive gates were analyzed in order to confirm or establish the placement of the 7 rays as well as to accurately determine the intensities of the 12 doublets, which included several not previously reported. A new ~ --fl interband transition, 4 + --+ 2~-(561.4 keV), a possible 3 + --*2~" (423.7 keV) transition, and a new 330.9 keV transition between the 4 + level and the I~K= 3-0 octupole level were established from coincidence data. Levels at 1757.0 keV in 152Sm and 1282.5, 1318.7, and 1692.2 keV in lS2Gd are now established on the basis of coincidence data. These data also establish for the first time the population in the 152Eu decay levels at 1680.0 and 1047.9 keV in 152Sm and 152Gd, respectively, as well as a new level at 1700.8 keV in 152Sm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
