Description
The band crossing in the Ba region has been studied in the extended interacting boson model in which to neutrons or two protons are coupled to a boson core. Energy levels, E2 ratios and g-factors are analyzed. A interesting feature in 128 Ba is the mixing of three bands, which is reasonably explained by the mixing of the pure-boson band, the boson + neutron pair band. In the analysis of 132 Ba, the isometric 10+ state is well described. The consistency of the boson-fermion interaction is investigated over eve-even and odd-A isotopes in the region. For example, is turns out the same quadrupole interaction between the odd neutron hole and bosons can account for the negative-parity states in 131 Ba and high-spin states in 132 Ba. (authors)
