Popis: In parallel experiments angular distributions of the differential cross sections and vector analyzing powers have been measured for the (d\ensuremath{\rightarrow}${,}^{3}$He) reactions on $^{204}\mathrm{Hg}$ and $^{206}\mathrm{Pb}$ at an incident deuteron energy of 79.1 MeV. The Q values for the reaction on $^{204}\mathrm{Hg}$ and a $^{202}\mathrm{Hg}$ contaminant were determined as -3340.9(3.4) keV and -2738.8(3.5) keV, respectively. Spectroscopic factors on $^{204}\mathrm{Hg}$ and $^{206}\mathrm{Pb}$ were obtained through a consistent distorted wave Born approximation (DWBA) analysis. A combined evaluation of relative spectroscopic factors and electron scattering (CERES) yields 3s-proton occupancies in $^{204}\mathrm{Hg}$ and $^{206}\mathrm{Pb}$. The latter is compatible with an earlier CERES result based on the more accurately known $^{206}--^{205}$Tl charge density difference. Substantial deviations from shell-model occupancies are observed.
