Theory references: consult the NSR database (www.nndc.bnl.gov/nsr/) for about 150 primary references dealing with nuclear structure and other calculations.

Levels: Band assignments and configurations are from 2014Li21 (also 2008Ma58) in ¹⁷⁶Yb(¹⁸O,4nγ)

Q-value: S(2n)=15628 5, S(2p)=10747.2 6 (2017Wa10)

E(level): From least-squares fit to Eγ values

J^π(level): When deduced from in-beam γ-ray datasets, it is assumed that levels with ascending spins are populated as the excitation energy increases. This is generally supported by systematics of such reactions and by decay modes. It is also assumed that transitions with quoted mult=D+Q and Q are M1⁺E2 and E2, respectively. The quoted ΔJ values are interpreted from γ(θ) data

M(γ): From ce data in ¹⁹⁰Au ε decay and (α,4nγ); γ(θ) data in (α,4nγ), and γγ(θ)(ADO) data in (¹⁸O,4nγ). Below 400 keV, ΔJ=2 (stretched) quadrupole transitions are assigned mult=(E2) in preference to M2, as no level lifetimes >10 ns or so are indicated in γγ-coin data in in-beam γ-ray data.

Double-beta decay mode is allowed, but only the lower limits of the half-life of this decay mode have been measured. g.s. band. T_1/2(level): Measured by 2017Br04 through the detection of the 3183-keV α emitted by ¹⁹⁰Pt with a total of 10103 101 events, after subtraction of 77 background events, resulting in decay rate of 133.1 13 counts per day from the decay of ¹⁹⁰Pt. The quoted uncertainty in half-life includes statistical as well as systematic, the two combined in quadrature. Authors compared their result with previous 13 measurements (eight from direct counting and five from geological methods), compiled and evaluated by 2006Ta01, and concluded that their measured value was in good agreement with an average value of 4.78×10¹¹ y 5 from geological methods, but not with averaged 3.9×10¹¹ y 2 from direct counting methods, which among themselves suffer from inconsistency. Others: 3.2×10¹¹ y 1 (1997Ta33); 6.65×10¹¹ y 28 (1987Al28,1986AlZT); 1966Ka23; 5.4×10¹¹ y 6 (1963Gr08, 6.8×10¹¹ y in 1961Gr37); 6.9×10¹¹ y 5 (1961Ma05); 4.7×10¹¹ y 17 (1961Pe23); 10×10¹¹ y (1954Po24, also 1956Po16,1953Po01); ≈5×10¹¹ y (1921Ho01). Geological measurements of half-life of ¹⁹⁰Pt: 8.8×10¹¹ y 7 (1991Wa32); 4.49×10¹¹ y 4 (1997Wa40; this value revised to 4.69×10¹¹ y 4 by 2001Be81); 4.7×10¹¹ y 3 (2002Mo47); 4.9×10¹¹ y 1 and 4.90×10¹¹ y 4 (2004Co30); revised to 5.1×10¹¹ y 1 and 5.08×10¹¹ y 5, respectively by 2006Ta01, considering the revised half-life of ¹⁸⁷Re. Evaluators obtain a weighted averaged (NRM approach) value of 4.93×10¹¹ y 10 from above 11 values listed with uncertainties, but using a minimum uncertainty of 0.1×10¹¹, with reduced χ²=3.8, somewhat larger than the critical χ²=1.8, implying that measured half-lives represent a discrepant dataset. See 2006Ta01 (also 2011Ta23) for compilation of experimental and theoretical α-decay half-lives of ¹⁹⁰Pt, statistical analysis and theoretical calculations. Partial measured half-lives to excited states of ¹⁸⁶Os: 2.6×10¹⁴ y +4-3(stat) 6(syst) (2011Be08) for the decay to the first 2⁺ state in ¹⁸⁶Os, and >3.6×10¹⁵ y (90% confidence level) to the first 4⁺ level in ¹⁸⁶Os (2011Be08). Half-life measurements for double-beta decay: \|>9.2×10¹⁵ y (2011Be32) for two-neutrino εβ⁺ decay mode to the g.s. of ¹⁹⁰Os. Also deduced in this work was the lower limit for 0-neutrino εβ⁺ decay to the ground state of ¹⁹⁰Os: T_1/2 \|>9.0×10¹⁵ y, and the lower limit for two-neutrino + 0-neutrino εβ⁺ decay to the first excited state of ¹⁹⁰Os: T_1/2\|>8.4×10¹⁵ y. α lower limit for the resonant 2ε capture to the 1382.4 keV level of ¹⁹⁰Os was also set: T_1/2\|>2.9×10¹⁶ y, along with limits for double electron capture from various combinations of the K and L shells (see 2011Be32 for details). Others: T_1/2(0νβε)>3.1x10¹¹ (1952Fr23,2002Tr04).
