Abstract

Several collective structures have been populated in the Z=55 nucleus Cs123 following the Pd108(19F,4n) fusion-evaporation reaction at a beam energy of 76 MeV. The low-lying structure is found to be dominated by a decoupled rotational band built on the unique-parityh11/2 orbital. Rotational structures based on the normal-parity g7/2 proton and the g9/2 proton-hole orbitals are also observed. Rotational alignments occur in the h11/2 band at Latin small letter h with strokec 0.44 MeV, and in the g9/2-1 band at Latin small letter h with strokec=0.38 MeV, both attributed to the rotational alignment of a pair of h11/2 neutrons, despite the different crossing frequency. In addition, the -vibrational band built on the h11/2 orbital has been observed feeding both signatures of the corresponding rotational cascade. These results are compared to cranked shell model calculations and to the systematics of the region.
