[en] The α-decay energy and halflife of ^195mAt were determined to be 6960±20 keV and 385⁺⁶⁹_-51 ms respectively, on the basis of genetic correlations in the ¹⁶⁹Tm(³⁶Ar, α6n)¹⁹⁵At reaction, while those of ^195gAt measured simultaneously were 7105±30 keV and 146⁺²¹_-17 ms respectively, reconfirming the previously reported values. A new isotope ¹⁹⁹Fr was also produced and identified in the same way in the ¹⁶⁹Tm(³⁶Ar,6n)¹⁹⁹Fr reaction, yielding E_α=7655±40 keV and T_1/2=12⁺¹⁰_-4 ms. (orig.)

[en] Nuclear spectroscopic information for known nuclides of mass number 199 (Os,Ir,Pt,Au,Hg,Tl,Pb,Bi,Po,At,Rn,Fr) with Z = 76 to 87 and N = 123 to 112 have been evaluated and presented together with adopted energies and Jπ of levels in these nuclei. No excited state data are available for ¹⁹⁹Os and ¹⁹⁹Fr, and very little information is available for levels in ¹⁹⁹Ir, ¹⁹⁹Rn and ¹⁹⁹At. The decay of ¹⁹⁹Ir to ¹⁹⁹Pt has not been studied. The decay of the 90-min activity of ¹⁹⁹Pb to ¹⁹⁹Tl is known in detail but remains unpublished in the open literature, while the decay of the 12.2-min isomer remains mostly unknown. The decays of the two activities of ¹⁹⁹Tl to ¹⁹⁹Pb are not known as separate decay scheme for each of the activities, thus only a composite decay scheme is presented. Similar is the case for the decay of the two activities of ¹⁹⁹Po to ¹⁹⁹Bi. In (³He,d) and (α,t) studies for ¹⁹⁹Au, disagreements are found between two independent contemporary studies. The most detailed structure known is for ¹⁹⁹Pb with five magnetic-rotational (MR) dipole bands together with many other dipole bands which are of probable multi-quasiparticle nature. This work supersedes previous evaluations of A = 199 published in update mode by 1994Ar13; as full A-chain updates by 1988Sc02, 1978Ha12 and 1971Le37; and a mid-stream update of ¹⁹⁹Pb nuclide by 2001Si44
