Simultaneous γ-ray and electron spectroscopy of ^{182, 184, 186}Hg isotopes

RADIOACTIVITY ^{182,182m,184,184m,186,186m}Tl(EC), (β⁺) [from U(p, F), E=1.4 GeV, UC_x target, selective ionization of isotopes of interest by resonance ionization laser ion source system at ISOLDE-CERN]; measured Eγ, Iγ, ce, γγ-coin, γ(ce)-coin, (ce)(ce)-coin using five HPGe clover detectors for γ radiation, and SPEDE spectrometer of 24-fold segmented, annular silicon detectors for conversion electrons (ce). ^182,184,186Hg; deduced levels, J, π, conversion coefficients, multipolarities, mixing ratios, E0 transitions, ρ²(E0), B(E2) ratios. Comparison with theoretical calculations using interacting boson model with configuration mixing (IBM-CM) from D1M parametrization of Gogny energy density functional, and with beyond mean-field (BMF) based model using SLy6 parametrization of Skyrme interaction. Detailed data for the decay schemes are provided in the Supplemental Material of the paper.
