Abstract: (APS)
Two-quasiparticle Kπ=8− isomeric states in the A∼130 and 180 regions are studied with configuration-constrained calculations of potential-energy surfaces. Strong shape-polarization effects due to the two quasiparticles are found. In particular, the nuclei 188Pb,186Hg, and 126Te can be polarized from ground-state spherical or oblate shapes to prolate shapes, indicating a combination of K isomerism and shape isomerism as the Fermi level approaches shell closure.- 27.60.+j
