Abstract
It is shown that 3 He impurities in sufficiently large 4 He systems adsorbed onto substrates with curved geometries form surface bound states, analogous to the Andreev state on a planar liquid--vapor interface. We report the analysis performed for superfluid 4 He adsorbed on the external surface of the nano-fullerene C 60 and on cylindrical nano-wires of Au. It is found that a single 3 He impurity diluted into such adsorbed structures behaves as on films on planar substrates and as on pure 4 He clusters.
