E(level): From least-squares fit to Eγ’s

Jπ(level): As proposed by 1997Ru03 based on γγ(θ)(DCO) data and band associations, with the exception that parentheses have been added by the evaluators when strong arguments are lacking. It is assumed that the spin ascend with excitation energy in heavy-ion fusion reactions

T1/2(level): For excited states, values are from neutron-gated recoil-distance method (1982Li08)

M(γ): From DCO ratios in 58Ni(28Si,2αγ) and RUL (when level lifetime is known)
