The energies and intensities of 77 $gamma$-ray transitions assigned to the electron-capture decay of $sup 206$Po have been measured. Multipolarities of transitions were determined from internal conversion coefficients calculated from our relative $gamma$-ray intensities and the relative conversion electron intensities of Fujika, Kanbe, and Hisatake. $gamma$-ray singles, $gamma$$-$$gamma$ coincidence, and previous conversion electron measurements were used to construct a more complete decay scheme for $sup 206$Po. Data obtained from in-beam reaction studies, $sup 210$At $alpha$ decay studies, and the present electron- capture decay scheme were used to identify states in $sup 206$Bi of a one proton particle-three neutron hole character. In addition a qualitative discussion of the level structure of $sup 206$Bi generated from (zero-order) couplings of 1h$sub 9$$/$$sub 2$ and 2f$sub 7$$/$$sub 2$ protons with the low-lying states of $sup 205$Pb is given, and this is compared with reasonable success to the experimental spectrum. The dominant electron-capture decay rates are explained in terms of an allowed single-particle mechanism. (AIP)
