$ 267Db has been observed as the α-decay daughter of 271Bh at JINR (2004Og03,2013Og01) and GSI (2013Ru11). Events were identified by the observation of chains of α-decaying nuclei, terminated by spontaneous fission. Comparison of the properties of the chains with those observed in previous studies allowed the assignment of individual decays 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.
