Collision-induced light scattering spectra and pair-polarizability trace and anisotropy of gaseous neon

New empirical pair-polarizability trace and anisotropy parameters, consistent with the spectroscopic measurements of neon gas at room temperature are obtained by fitting the calculated lineshapes and their first few even moments to the measured polarized and depolarized light scattering spectra. Good agreement with ab initio results in the literature is obtained and profiles calculated with these models are in excellent agreement with experiments.
