title: Recurrences in rotational dynamics and experimental measurement of superfluidity in doped helium clusters.
abstract: We present the first experimental evidence of recurrences in the rotational dynamics of doped helium clusters. Using the dopant molecule as an experimental microscopic probe of superfluidity, we show that in small He(N)-N2O complexes, superfluidity builds up in stages correlated with the filling and completion of a solvation shell.
