E(level): Two α groups are reported in 245Md α decay, with ΔQ(α)=41 28. These two groups define levels at E=x and E=x+41 28. If the highest-energy group feeds the g.s., then x=0

Q-value: Δ(Q(β-))=370, Δ(S(n))=460, Δ(S(p))=230 and Δ(Q(α))=210 (syst, 2012Wa38). The measured Eα group of 8113 20 gives Q(α)=8250 20 with the α group being a g.s. to g.s transition
