摘要：

The collision-induced rototranslational hyper-Rayleigh spectra of gaseous H-2-He mixture are computed and discussed in the binary regime. As the input data we use our ab initio computed H-2-He collision-induced first dipole hyperpolarizability tensor Delta beta(R). Both the vector and the septor part of the H-2-He hyper-Rayleigh spectra are evaluated at room temperature (T=295 K). The spectra are calculated assuming the full quantum computations based on the Schroumldinger equation of the relative translational motion in the isotropic H-2-He potential as well as using semiclassical methods.
