摘要
The adsorption of He-4 inside and outside a single fullerene C-60 is studied. A physisorption potential is proposed. The energetics and structural features of C-60-He-4(N) clusters are investigated within the framework of nonlocal density functionals. Particular attention is paid to the growth of the highly pronounced layered density profile. The evolution towards bulk liquid and surface thickness at the free interface are discussed.
