Evolution of octupole correlations in ¹²³Ba

NUCLEAR REACTIONS ¹⁰⁸Cd(¹⁹F, 3np), E=90 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(DCO) at HI-13 tandem facility of the CIAE-Beijing. ¹²³Ba; deduced high-spin levels, J, π, bands, multipolarity, B(E1)/B(E2) ratio. ^123,125,145Ba; systematics of B(E1)/B(E2) ratios, theoretical and experimental energy displacements between the opposite-parity bands, octupole correlations, potential-energy surface contours in (β₂, β₃) plane. Comparison with predictions of multidimensionally-constrained relativistic mean-field (MDC-RMF) model, and cluster model based on dinuclear system.
