E(level): From least-squares fit to Eγ values
Jπ(level): For high-spin states (J>5) the assignments are from 1996Al16 in (58Ni,3pnγ),(40Ca,3pnγ) with the parentheses added by the evaluators. These are based on ΔJ and multipolarity assignments deduced from γ(θ) and Doppler-broadening data
M(γ): From γ(θ) in (58Ni,3pnγ),(40Ca,3pnγ) for transitions from high-spin (J|>5) states with ΔJ=1 for d or D+Q and ΔJ=2 for Q, and from ce data in 100Cd ε decay for transitions from low-spin (J<5) states, unless otherwise noted.

Theory references: consult the NSR database (www.nndc.bnl.gov/nsr/) for four primary references, three dealing with nuclear structure calculations and one with decay modes and half-lives.
101In with g.s. half-life of 15.1 s is a potential delayed proton emitter with Q(εp)=2240 200 (syst, 2017Wa10), which could populate levels in 100Ag, but no proton measurements have yet been reported.
Levels: See 1996Al16 for proposed neutron-proton (multiparticle) configuration assignments to several high-spin (J|>5) levels based on comparisons with shell-model calculations
Levels: No level populations are known from 101In εp decay (15.1 s)
Q-value: S(2n)=21210 30, S(2p)=9541 13, Q(εp)=154 8 (2017Wa10)
