ResumoPhotoionization efficiency data for Hg2+ have been obtained in the region of 650–1400 A. The ionization energy of Hg2 was determined to be 9.103 ± 0.010 eV. This value allows the calculation of the dissociation energy of Hg+2 to be 1.40 ± 0.02 eV. By analyzing the differences in energy between corresponding autoionization peaks observed in the Hg+ and the Hg2+ spectra and by assuming the charge induced-dipole interaction to be the dominant interaction between Hg+(2D5/2, 3/2) and Hg at the equilibrium bond distance of Hg2, the equilibrium bond distance for Hg2 was deduced to 3.35 A.
