Mass measurement: 2011Et01 (Penning-trap using TITAN at TRIUMF), 2007Ke09, 1994Ot01, 1979Ep01

Nuclear structure calculations: 1980Ca23, 2007Wy01

Q-value: S(2n)=27280 100 (syst), S(2p)=8149 7, Q(εp)=781 6 (2012Wa38)

E(level): From least-squares fit to Eγ’s, assuming Δ(Eγ)=1 keV

Jπ(level): From band assignments (1997Gr07) based on neighboring odd-A Br and Rb isotopes

E(γ): Uncertainty is less than 1 keV for low energy strong γ rays and up to 2 keV for transitions near the top of bands
