E(level): Levels not connected to any other level are taken from 74Se(p,t); other level energies are calculated from the adopted Eγ data.

Jπ(level): From γ(θ) in (HI,xnγ) and γ decay mode, except as noted.

T1/2(level): From (HI,xnγ), except as noted.

E(γ): γ data from levels above 3.3 MeV are from (HI,xnγ); for other γ radiations, data are from 72Br ε decay and (HI,xnγ); averages have been calculated where possible.

M(γ): Mult=E2 from γ(θ) in (HI,xnγ) and RUL, except as noted.
