Abstract : A statistical theory is given for the refractive index of non polar gases at low densities, taking into account both the effect of statistical fluctuations and the effect of the variation of the polarizability due to molecular interactions. A generalized Lorentz-Lorenz formula is derived and numerical calculations are performed for helium. For the highest frequencies considered the correction to the Lorentz-Lorenz function is about 15% larger than the corresponding correction to the ClausiusMosotti function. (Author)
