英文摘要 | High-spin states of Ba-123 have been studied via the Cd-108(F-19,3np)Ba-123 fusion-evaporation reaction at a beam energy of 90 MeV. Several E1 transitions linking the positive-parity nu(d(5/2) + g(7/2)) band and negative-parity nu h(11/2) band are observed in 123Ba for the first time. Evidence for the existence of octupole correlations in Ba-123 is presented based on the systematic comparisons of the B(E1)/B(E2) branching ratios and the energy displacements in odd-A Ba isotopes. The characteristics of octupole correlation in the odd-A Ba-123,Ba-125 are explained by the state-of-the-art multidimensionally-constrained relativistic mean-field model and cluster model based on the dinuclear system concept. |
