Abstract

Excited states have been observed for the first time in the very neutron-deficient Cs-114(55)59 nucleus. The assignment to Cs-114 was made by detecting gamma rays in coincidence with evaporated charged particles and with recoiling evaporation residues. A rotational band has been observed up to spin 21h (tentatively 25h). Excitation-energy systematics and a study of quasiparticle alignments suggest that the band is based on the nu(h(11/2))circle times pi(h(11/2)) configuration. Unlike bands based on this configuration in heavier cesium isotopes, only one signature partner is observed, and there is no evidence for signature inversion. These observations agree with theoretical calculations which predict that Coriolis-induced signature splitting should dominate at N=59.
