Résumé :

THE second virial coefficient of krypton was determined for temperatures ranging from 109.95°K. to 270.3°K. The experimental technique has been described1,2; one measures the difference between the volume expansions at the same pressure and temperature of krypton and hydrogen chosen as a standard of reference. The advantage of this method is that one can neglect the virial coefficients of higher order than the second. Commercial 'pure grade' krypton gas, supplied by Air Liquide S.A. Paris, was purified by distillation at low temperatures. © 1962 Nature Publishing Group.
