Résumé
Ayant amélioré la mesure du coefficient de diffusion D pour des solutions diluées de 3He dans 4He solide, on présente de nouveaux résultats pour des concentrations x3 en 3He comprises entre 10-2 et 10-4. Le produit Dx3 n'est constant que si l'on a x3 < 3 x 10-4.
Abstract
Improved measurements of the diffusion coefficient D are reported for dilute solutions of 3He in solid 4He at fractional impurity content (x3) from 10-2 to 10-4. Dx3 does not become constant until x3 < 3 x 10-4.
