Résumé
Nous avons mesuré la chaleur spécifique-des mélanges 3He/4He , x = 0,070 ; 0,129 ; 0,245 ; 0,328 dans l'intervalle 3 x 10-6K ≤ |T - Tλ| 10-2K. Nos valeurs expérimentales de l'exposant critique αφ le long de la courbe à différence de potentiel chimique constant sont indépendantes de x.
Abstract
The specific heat under saturated vapour pressure of 3He/4He mixtures with 3He mole fraction x = 0.070, 0.129, 0.245, 0.328 has been measured near the λ transition in the temperature range, 3 x 10-6K ≤ |T - T λ| 10-2K. The critical exponent αφ along the path of constant chemical potential difference was found to be independent of x.
