Abstract

The yrast and yrare states based on the νh_<11/2>xotimeπh_<11/2> configuration in the odd-odd nucleus ^<134>La are investigated within the framework of a pair-truncated shell model. The model accurately reproduces the experimental energy levels and ratios B(M1; I→I-1)/B(E2; I→I-2) of the yrast states. It turns out that the yrast and yrare states can be classified in terms of △I=2 E2 bands that are composed of different angular momentum configurations of an unpaired neutron and an unpaired proton, weakly coupled with the quadrupole collective excitations of the even-even core.
