E(level): From least-squares fit to Eγ values for levels populated in γ-ray studies.

Jπ(level): In assigning high Jπ values the evaluators assume that spins tend to increase with excitation energy, particularly for higher-lying levels. In (p,t), only L=0 and L=2 are considered as reliable.

T1/2(level): LABEL=T1/2 or Γ

Additional Gamma Comments:

E(level)E(gamma)Comments
   1076.789   1076.782E(γ): weighted average from 1076.785 10 (2021Kr05, 86Rb β- decay), 1076.66 9 (2020Gu18, 86Y ε decay), 1076.772 75 (2016Ma49, 86Rb β- decay) and 1076.63 10 (1970Ra06, 86Y ε decay). Other: 1076.64 4 (1986Wa25, in-beam γ-data) not used in the averaging procedure as it gives a large χ2.
   2641.25   1564.49I(γ): From 86Y ε+β+ decay.
   2641.12I(γ): From 86Y ε+β+ decay.
   2672.67    190.73I(γ): Weighted average from the rather discrepant values reported in various measurements, ranging from 5.9 7 in 87Rb(p,2nγ) to 22.1 8 in 82Se(9Be,5nγ).
   1595.8M(γ): from γγ angular correlations in (p,2nγ) (2017Du08).
   2857.06    184.42I(γ): weighted average of values from (9Be,5nγ) and (13C,3nγ). In 87Rb(p,2nγ) a branching ratio of 23.7 14 is given.
    627.44M(γ): from γ(θ) and γ(lin pol) in (18O,2nγ)
   2955.74     98.68M(γ): from α deduced from intensity balance in IT decay.
   2997.01   1140.3E(γ): Poor fit, the level-energy difference is 1142.89 8. Transition observed only in 87Rb(p,2nγ) (2017Du08).
   3055.70    825.89M(γ): [M2+E3] in 82Se(9Be,5nγ) from DCO (2014Li25) seems unlikely in view of short half-life of 3055.87 level.
   3291.18    235.33M(γ): from DCO in 82Se(9Be,5nγ) (2014Li25), 76Ge(13C,3nγ) (2016Ku17) and in 87Rb(p,2nγ) (2017Du08).
   3317.79    439.57I(γ): from 86Y ε+β+ decay.
    644.99I(γ): from 86Y ε+β+ decay.
   3430.15   3429.94M(γ): From γγ(θ) in 86Y ε+β+ decay (14.74 h).
   3491.02   1261.00I(γ): from 86Y ε+β+ decay (14.74 h).
   1636.98I(γ): from 86Y ε+β+ decay (14.74 h).
   2414.31I(γ): from 86Y ε+β+ decay (14.74 h).
   3644.62    765.7I(γ): from 87Rb(p,2nγ)
   1790.7I(γ): from 86Y ε+β+ decay (14.74 h).

   3871.20   1229.5I(γ): from 86Y ε+β+ decay.
   3904.02   1673.8I(γ): from 86Y ε+β+ decay.
   3925.66    370.05I(γ): from 86Y ε+β+ decay. Other: 85 14 in 87Rb(p,2nγ).
   4441.26   1386.1I(γ): from 86Y ε+β+ decay.
   4708.81   1753.03M(γ): from γ(θ) and γ(lin pol) in (18O,2nγ), and from DCO in 76Ge(13C,3nγ)
E(level)E(gamma)Comments
   4924.3   1260.2M(γ): from DCO in 76Ge(13C,3nγ) (2016Ku17)
   5834.4   1125.54E(γ): 1128.5 3 in (α,2nγ) was not used in averaging as it appears discrepant by ≈3 keV, as compared to values from three other reactions
   6190.9    129.83M(γ): from γ(θ); γ(lin pol) in (18O,2nγ)
   6687.6   1026.8M(γ): from 82Se(9Be,5nγ) (2014Li25). E2 in (13C,3nγ) (2016Ku17) is incorrect
   6879.0    674.4M(γ): ΔJ=0 transition in (13C,3nγ) (2016Ku17).
