A modern version of the Burnett apparatus was constructed and subsequently employed to experimental determine the pressure-volumetemperature behavior of the helium-krypton system. Measurements were made on the -50, 0 and +50�c isotherms over a pressure range of 7 to 150 atm. The results of this work were compared to previous works and then combined with selected previous values to form an appropriate basis for a study of molecular interactions utilizing the Kihara intermolecular potential function.Chemical Engineerin
