Description

The thermal conductivity lambda of 4He and 3He has been measured in the temperature range 25-100 deg C and from atmospheric pressure up to 800 bars. The experimental ratio (lambda 4He)sub(P,T)/(lambda 3He)sub(P,T) has been found to be 2% higher than the theoretical value deduced from the corresponding state principle

Abstract (French)

La conductivite thermique lambda de l'helium 4 et de l'helium 3 a ete mesuree dans le domaine de temperature 25-100 deg C, de la pression atmospherique jusqu'a 800 bars. Le rapport experimental (lambda 4He)sub(P,T)/(lambda 3He)sub(P,T) a ete trouve superieur d'environ 2% au rapport theorique deduit de l'application du principe des etats correspondants
