Theoretical photoionization cross sections, angular distributions, and spin-polarization parameters for outer $\mathrm{ns}$ and $\mathrm{}(n-1\mathrm{})d$ subshells of the group-$\mathrm{II}B$ elements zinc, cadmium, and mercury are determined above their respective $\mathrm{}(n-1\mathrm{})d$ thresholds. Account is taken of electron-electron correlation and of the spin-orbit interaction by means of the relativistic random-phase approximation. Comparisons are made with previous theoretical work and with available experimental measurements.
