E(level): Levels connected by gammas are from least squares fit, others from 54Fe(p,t), except where seen only in (3He,n).

Jπ(level): From L value in 54Fe(p,t), with S=0 neutron pair transfer assumed, except as noted.

T1/2(level): DSAM, from 28Si(28Si,2p2nγ), except as noted.

M(γ): From values of R(ado) in 28Si(28Si,2p2nγ) and using RULER to rule out mults, except as noted.
