摘要：
Path-integral Monte Carlo calculations have been used to study small clusters of p-H-2 molecules at low temperatures. Below about 2 K, clusters of 13 and 18 molecules exhibit manifestations of superfluid behavior. However, exchange permutation of molecules is greatly suppressed in a cluster of 33 molecules, even at 1 K.
