  A  283Nh α decay (0.07 S) 

General Comments:

$ 279Rg has been observed as the α-decay product of 283Nh at JINR (2004Og03,2013Og01) and GSI (2013Ru11). Events were identified by the observation of chains of correlated α decays, terminated by spontaneous fission. Comparison of the properties of the decay chains to those previously observed in the literature allowed the assignment of individual decays to specific isotopes.

$ 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.
