Detailed α-decay study of ¹⁸⁰Tl

RADIOACTIVITY ¹⁸⁰Tl(α)[from U(p, X), E=1.4 GeV using Resonance Ionization Laser Ion Source (RILIS) and HRS separator at ISOLDE-CERN facility]; measured Eα, Iα, Eγ, Iγ, E(x ray), I(x ray), αγ- and αγγ-coin. ¹⁷⁶Au; deduced levels, α-decay branching ratios, reduced α-widths, total and K-conversion coefficients, multipolarities, configurations, population of only the low-spin activity in ¹⁷⁶Au from ¹⁸⁰Tl α decay. Comparison with previous experimental data. Systematics of α-reduced widths in α-decays of ^{178,180,182,184}Tl. ¹⁸⁰Hg(α)[from ¹⁸⁰Tl ϵ decay]; ¹⁷⁶Au(α)[from ¹⁸⁰Tl α decay]; ¹⁷⁶Pt(α)[from ¹⁸⁰Hg α decay]; measured Eα, Eγ, αγ-coin. ¹⁷²Ir; deduced level, low-spin activity in ¹⁷²Ir populated by ¹⁷⁶Au α decay.
