Abstract: We describe an absorption spectroscopy experiment at 194 nm on Hg+, ground-state atomic mercury ions, and at visible wavelengths on Hg*, excited 63Po mercury atoms in Hg-Ar discharges. This experiment is used to map the absolute density of Hg+ and Hg* in the cathode region of Hg-Ar discharge lamps operated in the hot-cathode mode. [ABSTRACT FROM AUTHOR]
