Shape coexistence and multiparticle-multihole structures in ^{110, 112}Cd

RADIOACTIVITY ^110,112In(β⁺), (EC)[from Ta(p, X), E=500 MeV]; ¹¹²Ag(β^-)[from Ta(p, X), E=500 MeV]; measured Eγ, Iγ, and γγ-coin using 8π HPGe detector array at TRIUMF-ISAC. ^110,112Cd; deduced levels, J, π, branching ratios, B(E2), configurations. Comparison of experimental B(E2) values with beyond mean-field calculations. Discussed shape-coexisting intruder band and multiparticle-multihole proton excitations for the second, third and fourth excited 0⁺ levels of ^110,112Cd.

NUCLEAR REACTIONS ^110,112Cd(n, n'), E=2.1-3.4 MeV; analyzed earlier γ(θ) and DSAM data; deduced half-lives of excited states.

NUCLEAR STRUCTURE ^110,112Cd; calculated levels, J, π, B(E2), collective wave function contours in the (β₂, γ) plane for excited states using symmetry conserving configuration mixing method (SCCM), B(E2) by beyond mean-field method. Comparison with experimental data.
