Sažetak
Two, three and four ^3He and ^4He atoms in quasi two-dimensional space above graphite and cesium surfaces and in "harmonic" potential perpendicular to the surface have been studied. Using some previously examined variational wave functions and Diffusion Monte Carlo procedure it has been shown that all molecules: dimers, trimers and tetramers, are bound stronger than in pure two- and thee-dimensional space. The enhancement of binding with respect to unrestricted space is more pronounced on cesium than on graphite. Furthermore, for ^3He on all studied surfaces there is indication that the configuration of a dimer and a "free" particle is more stable than the trimer.
