COMMENTS: The experimental apparatus consisted of a light source, either a 30 W deuterium (D2) lamp or a low-power Hg (184.95 nm) atomic lamp, a 90.4 ± 0.3 cm long absorption cell, and a 0.25m monochromator (150 μm entrance slit and ∼ 1nm (full width at half maximum) resolution) equipped with a photomultiplier tube detector or a solar blind photodiode detector (for the Hg atomic line at 184.95nm)

Parameterization of the temperature dependence valid over the wavelength range 192.5 to 240 nm for temperatures between 213 and 323 K

ln (σ(λ,T)) = ∑i Ai (λ - 200)i + (T - 273) ∑i Bi (λ - 200)i
