$ 273Hs has been observed as the α-decay daughter of 277Ds at LBNL (2010El06) and JINR (2015Ut02,2018Ut02). Events were identified based on the observation of chains of correlated α decays, terminated by spontaneous fission. Comparison of the properties of these chains with previous observations 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.
