摘要：Excited states in Sb120 have been investigated using the Cd116(Li7,3n)Sb120 reaction at a beam energy of 34 MeV. A total of 15 new γ rays were added into the level scheme of Sb120. Most of the observed single-particle states can be interpreted in terms of weak coupling of the odd proton and odd neutron to an excited Sn118 core involving either vibrational states or broken neutron pairs. The previously known strongly coupled rotational band based on the πg9/2-1 - νh11/2 configuration has been extended up to the (15-) state. The configuration-fixed constrained triaxial relativistic mean-field approaches and the particle rotor model are employed to discuss the high-spin isomers and strongly coupled rotational band, respectively. © 2014 American Physical Society.
