Abstract
We report on the hysteresis and avalanche behavior of He-4 capillary c ondensing into the nearly cylindrical pores of the porous membrane Nuc lepore. Following capillary condensation, withdrawal of the He-4 resul ts in distinct jumps or avalanches where 10(7) pores can be involved i n a single avalanche. By using Nuclepore with 2000 Angstrom and 300 An gstrom pore diameters, we find that the avalanche distribution depends on details of the pore structure.
