摘要：

The nuclear magnetic susceptibility of He-3 adsorbed on the surface of graphite, plated with a monolayer of solid He-4, has been measured at surface densities less than 0.055 angstrom-2 and at temperatures down to 6 mK. A temperature-independent susceptibility is observed at low temperatures, which is strongly enhanced over the ideal-gas value, due to quasiparticle interactions. The inferred Landau-Fermi-liquid parameters allow a comparison with microscopic theories of interacting Fermi systems.
