Abstract

We present a microscopic analysis of the quantum solvation structures of para-H2_2 around the OCS molecule when embedded in low temperature 4^4He droplets. The structures of clusters containing M=5 and 6 para-H2_2 molecules are compared with corresponding structures for M=1 (OCS-H2_2 complex) and M=17 (a full solvation shell), as well as with the clusters in the absence of helium. We find that the helium has negligible effect on the structures for the small and large OCS(H2_2)M_M clusters, but that it modifies the cluster structure for M=6. We discuss implications of these results for the onset of superfluidity in the solvating hydrogen shell and for spectroscopic measurements.
