Abstract High-spin levels in125Ba have been produced in the116Sn(12 C, 3n) reaction and studied by in-beam spectroscopic methods. Two strongly populated band structures are observed. The odd-parity one is based on a 7/2− state and can be explained as the result of the coupling between anh 11/2 neutron-hole and a prolate type triaxial core. The even-parity band, built on a 7/2+ state, corresponds to collective excitations associated with a neutron-hole in theg 7/2 shell. Comparisons with heavier odd-A Ba isotopes and discussions are made in the frame work of the triaxial core model. Nuclear Reactions116Sn(12C, 3nγ), E=45–55 MeV; measuredσ(E;E γ,θ),γγ-coinc,γ-γ delay.
