| 0.0 | (3/2-) | 1.1 m 1 % ε = 60 10 % α = 40 10 | ε/(α+ε)=0.60 10 was deduced by 1973Es01 from comparison of the maxima of excitation curves for 249Md and 245Es α activities in 241Am(12C,X) reactions. α/ε=0.20 5, which gives %ε=83 4, was obtained by 1967Mi06 from the yields for 245Cf and 245Es α’s. E(level): ε/(α+ε)=0.60 10 was deduced by 1973Es01 from comparison of the maxima of excitation curves for 249Md and 245Es α activities in 241Am(12C,X) reactions. α/ε=0.20 5, which gives %ε=83 4, was obtained by 1967Mi06 from the yields for 245Cf and 245Es α’s. |
