Abstract
The very neutron-deficient strongly deformed Cs119 nucleus has been studied using the Ni58(Zn64,3p) reaction and the JUROGAM 3 γ-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≈120 mass region.8 MoreReceived 29 March 2021Revised 29 July 2021Accepted 24 September 2021DOI:https://doi.org/10.1103/PhysRevC.104.044305©2021 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasCollective levelsLifetimes & widthsNuclear structure & decaysTransfer reactionsProperties90 ≤ A ≤ 149Nuclear Physics
