Abstract

Nuclear Theory

Physics

The reduced transition probabilities for the 41+ → 21+ and 21+ → 01+ transitions in Mo92 and Ru94 and for the 41+ → 21+ and 61+ → 41+ transitions in Zr90 have been determined in this experiment making use of a multinucleon transfer reaction. These results have been interpreted on the basis of realistic shell-model calculations in the f5 / 2 , p3 / 2 , p1 / 2 , and g9 / 2 proton valence space. Only the combination of extensive lifetime information and large scale shell-model calculations allowed the extent of the seniority conservation in the N=50 g9 / 2 orbital to be understood. The conclusion is that seniority is largely conserved in the first πg9 / 2 orbital.
