  A  271Sg α decay (96 S) 

General Comments:

$ 267Rf has been observed as the α-decay daughter of 271Sg at JINR (2004Og12,2006Og05). Events were identified by the observation of chains of α-decaying nuclei, terminated by spontaneous fission. The properties of these chains, when compared to those previously observed, allowed individual decays to be assigned to specific nuclei.

$ Half-lives, branching ratios, and α-decay energies in this evaluation have been computed from the individual events listed in the references above. Half-life uncertainties have been computed according to the method of 1984Sc13. An additional 10 keV systematic uncertainty is assumed for the α-decay energies, which is added in quadrature to the averaged statistical uncertainty.

Q-value: ΔQ(β-)=686, ΔS(n)=707, ΔS(p)=788, ΔQ(α)=300 (2021Wa16)

Q-value: S(2n)=11389 syst 678 (2021Wa16)
