Three-body interaction-induced light scattering in krypton gas: a computer simulation of the spectral line shapes

摘要: The two-, three- and four-body effective collision induced scattering spectral line shapes are calculated for dense gaseous krypton using the pairwise additivity (PA) approximation different polarizability models. These spectra several interaction at various densities compared with experimental measurements of Barocchi et al. [1988, Europhys. Lett., 5, 607]. potential effect on spectrum is found to be weak. results obtained Meinander [1986, J. chem. Phys., 84, 3005] empirical model molecular dynamics fit well two- three-body shapes. irreducible contribution shape evaluated dipole [buckingham, A. D., Hands, I. 1991, Chem. Phys. 185, 544]. This relatively weak anisotropic in frequency density range studied, explaining good agreement between p...
