The autoionization region of mercury was investigated with spin- and angle-resolved photoelectron spectroscopy between the Hg<sup>+</sup> (5d<sup>9</sup> 6s<sup>2</sup>)<sup>2</sup>D<sub>5/2</sub> and Hg<sup>+</sup> (5d<sup>9</sup> 6s<sup>2</sup>)<sup>2</sup>D<sub>3/2</sub> thresholds. Spin-polarization parameters A and ξ and intensity were measured separately for the photoelectrons corresponding to the two final ionic states accessible (<sup>2</sup>S<sub>1/2</sub>, <sup>2</sup>D<sub>5/2</sub>) as function of the radiation wavelength. The data are dominated by structure due to autoionization resonances and differ quantitatively for the two peaks in the photoelectron spectra. The results are compared with earlier measurements below the <sup>2</sup>D<sub>5/2</sub>-threshold.
