The collective band structures of the 125Cs nucleus have been investigated by in-beam γ-ray spectroscopic techniques following the 110Pd ( 19F, 4n) reaction at 75MeV. The previously known level scheme, with rotational bands built on πg 7/2, πg 9/2 and πh 11/2 orbitals, has been extended and evolves into bands involving rotationally aligned ν(h 11/2)2 and π(h 11/2)2 quasiparticles. A strongly coupled band has been reassigned a high-K πh 11/2 ⊗ νg 7/2 ⊗ νh 11/2 three-quasiparticle configuration and a new side band likely to be its chiral partner has been identified. Configurations assigned to various bands are discussed in the framework of Principal/Tilted Axis Cranking (PAC/TAC) model calculations.
