Abstract
An apparatus designed to measure the refractive indices of the inert gases over the temperature range 77 to 273°K and at pressures up to 100 atm is described. Techniques are given for calibration of the optical cell and the production of a suitable solid specimen. The accuracy of the method is discussed and it is shown how polarizability and compressibility may be deduced from the refractive index data.Keywords
