Abstract
High-spin states of 124Ba, 125Ba and 125Cs have been populated in the reactions 110Cd + 18O at 80MeV and 96Zr + 34S at 160 MeV and studied using nuclear spectroscopy techniques. Several bands have been established in 124Ba and previously known band structures in 125Ba and 125Cs extended up to ( 43 2 − ) levels. Results concerning crossing frequencies and quasiparticle configurations are deduced from experimental routhians and aligned angular momenta. We propose that the two positive-parity bands in 124Ba are generated by h 11 2 proton and h 11 2 neutron alignments and the three negative-parity bands by the coupling of h 11 2 , g 7 2 neutrons and h 11 2 , g 7 2 or g 9 2 protons.
