Complete set of proton excitations in Cs-119

• The very neutron-deficient strongly deformed Cs-119 nucleus has been studied using the Ni-58(Zn-64, 3p) reaction and the JUROGAM 3 gamma-ray detector array coupled to the MARA recoil-mass separator setup. The excitation energies of all observed bands have been determined, spins and parities have been firmly assigned to most of the observed states. The previously known and the newly identified rotational bands have been extended to very high spin and excitation energy. The configurations of the observed bands are discussed using the particle number conserving cranked shell model. The present study establishes the largest set of rotational bands observed in the proton-rich A approximate to 120 mass region.
