Abstract
Previous experiments have shown that it is possible to nucleate localized states of 3He near a solid wall at pressures below the melting pressure and at temperatures below 100 mK. We have further investigated the question of solid nucleation of He by carrying ou superfluid 4He oscillations experiments through a Vycor superleak as a function of pressure and of temperature above 1 K. We find that, contrary to calculation, superflow continues right up to the melting curve and no blocking of the capillary due to filling with solid is observed
