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.Keywords
