Prolate-oblate asymmetric shape phase transition in the interacting boson model with SU(3) higher-order interactions

NUCLEAR STRUCTURE ¹⁸⁰Hf, ^182,184,186W, ^188,190,192Os, ^194,196Pt, ^198,200Hg; calculated excitation energies for yrast band, J, π, yrast band structure, B(E2), quadrupole moment, prolate-oblate shape phase transition. Interacting boson model with SU(3) higher-order interactions (SU3-IBM). Point out that the average deformation of the prolate shape is nearly twice the one of the oblate shape. Comparison to experimental results.
