1991Ma65: Interacting Boson-Fermion Model used to interpret levels in ¹⁹⁹Au

Q-value: Note: Current evaluation has used the following Q record $ 452.0 6 7584.25 15 6476 3 169.9 17 2003Au03

E(level): From least-squares fit to adopted Eγ’s for levels seen in ¹⁹⁹Pt β^- decay and ¹⁹⁸Au(n,γ), omitting doublets from the fitting procedure. From (t,p) and/or (³He,d) for levels seen in reaction experiments only. The uncertainties for levels above 1300 keV from (³He,d) may be underestimated due to possible calibration problems

J^π(level): In ¹⁹⁷Au(t,p), Jπ(¹⁹⁷Au target)=3/2⁺. Above 1 MeV, the data available for (³He,d) and (α,t) from 1980AtZZ and 1978Mu08 are not in very good agreement. For this reason L(³He,d) values for levels above 1 MeV are considered as tentative, except for a strongly populated 1861 level (1849 is the ’adopted’ energy) for which L=5 seems quite definitive from both studies.

T_1/2(level): From ¹⁹⁹Pt β^- decay, unless otherwise noted

E(γ): From ¹⁹⁸Au(n,γ) data where available, otherwise from ¹⁹⁹Pt β^- decay.

I(γ): Weighted average of measurements in ¹⁹⁹Pt β^- decay and ¹⁹⁸Au(n,γ), unless otherwise noted.
