  We have performed a shell-model study of the two nuclei 210Po and 206Hg,
having and lacking two protons with respect to doubly magic 208Pb. In our
calculations we have employed realistic effective interactions derived from the
Bonn A nucleon-nucleon potential. The calculated results are compared with the
available experimental data are, however, very scanty for 206Hg. The very good
agreement obtained for 210Po supports confidence in our predictions for 206Hg.
