Abstract.

Band structures of the 123Cs nucleus have been investigated using the 100Mo(28Si, p4n) reaction at a beam energy of 130 MeV. The previously observed rotational bands based on \(\) h 11/2, \(\) g 7/2 and \(\) g 9/2 orbitals have been extended. The excitation energies of these bands have been established with the help of interband transitions and those connecting to the low-energy levels established from the \(\) + /EC decay of 123Ba (T 1/2 = 2.7 m). The bandhead of the \(\) g 9/2 band at the 328.1 keV (\(I^{\ensuremath{\pi}} = 9/2^{ + }\)) is proposed to be isomeric following arguments based on the intensity balance of the feeding and de-exciting \(\) transitions. New multiquasiparticle bands based on \(\) \(h_{11/2}\otimes \ensuremath{\nu}h_{11/2} \otimes \nu g_{7/2}\), \(\) \(g_{7/2} \otimes \pi(h_{11/2})^{2}\) and \(\) \(g_{7/2} \otimes \pi (h_{11/2})^{2} \otimes \nu(h_{11/2})^{2}\) configurations have been identified.
