Abstract

High-spin states in the doubly odd $N = 77$ nucleus $^{132} Cs$ have been studied. The known positive-parity structures have been extended. $γ$ -ray linear-polarization and angular-correlation measurements have been performed to establish the spin and parity assignment of these structures. A new chiral partner of the $π h_{11 / 2} \otimes ν h_{11 / 2}$ band has been proposed. Three-dimensional tilted axis cranking model calculations have been performed and compared with the experimental results.
