Translational absorption band in low density mixtures of noble gases: the He-Xe case

Abstract
Room temperature absorption measurements were performed in the farinfrared region on low-density He-Xe mixtures. The complete spectral shape of the binary absorption coefficient A(v) has been determined with good accuracy. Detailed line-shape analysis of the translational band yielded reliable values of the spectral moments γ0, γ2, and γ4. Through a spectral moment analysis, we determine the range ρ and the intensity μ0 of the dipole moment induced in the He-Xe pair.
