Résumé
La décroissance de la densité superfluide et l'abaissement de la température d'apparition de la superfluidité dans l'hélium II ont été mesurés dans les pores cylindriques ayant 0,10 ; 0,08 ; 0,05 et 0,03 µm de diamètre qui traversent des membranes ayant 5,0 µm d'épaisseur (Nuclepore).
Abstract
The reduction of the superfluid density of liquid 4 Hell and the lowering of the superfluid onset temperature have been studied in 0.10, 0.08, 0.05 and 0.03 um diameter cylindrical pores through 5.0 µm thick polycarbonate films (Nuclepore).
