Abstract
We have measured the suppression of superfluidity of liquid in small cylindrical pores. The suppression is smaller than calculated by recent theories, and indicates that a dissipative state intervenes before true superflow through the pores commences. The critical currents are two orders of magnitude lower than those measured in the bulk, and do not show the same power-law behavior.
