$ 271Hs has been observed in gas-phase chemistry experiments at GSI (2006Dv01,2008Dv02). Events were identified based on the observation of chains of α-decaying nuclei correlated in time and position.
$ 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.
