Résumé
La tension superficielle à l'interface entre les phases liquides séparées de mélanges 3He-4He a été étudiée en fonction de la température de 0,3 K à 0,7 K, et de la pression entre la pression de vapeur saturante et vingt atmosphères. La hauteur du ménisque mesurée depuis sa base, a été déterminée par une technique d'interferometrie holographique.
Abstract
The interfacial surface tension of phase separated 3He-4He liquid mixtures has been studied as a function of temperature from 0.3 K to 0.7 K and of pressure from saturated vapor pressure to twenty atmospheres. The technique of real time holographic interferometry has been used in determining the height of the interfacial meniscus as measured from its bottom.
