Abstract

The new technique of Wampler and Gentry for determining the temperature and density of a gas by measuring UV gas absorption at two wavelengths [ F. B. Wampler and R. A. Gentry, J. Appl. Phys. 52, 15831981)] has been applied to gaseous UF6. At 266 nm the absorption cross section σ of UF6 appears to be constant, σ = (1.15 ± 0.01) 10−18 cm2 from 0–100°C. The absorption cross section at 245 nm over the same temperature range may be represented with the empirical polynomial σ = [1.37 ± 0.05 + (9.7 ± 1.5) 10−3T − (4.2 ± 1.1)10−5T2] 10−18 cm2, where T is in degrees Celsius. Differences in (dσ/dT)λ at 266 and 245 nm allow both UF6 temperature and density to be determined by UV absorption measurements. The strengths and limitations of this technique are discussed.
