摘要：
A degenerate Fermi fluid has been realized recently for 3He films adsorbed in one-dimensional (1D) pores 28 Å in diameter, preplated with 4He layers. In order to study the influence of the 4He preplating on the 3He Fermi fluids, heat capacity was measured down to 4 mK for two preplated 4He films of different thickness. At low temperatures, no substantial difference was found between the two cases. On the other hand, a large difference appeared above about 150 mK. The large 3He heat capacity for the thick 4He preplating suggests thermal excitation of the 3He atoms to the excited energy levels of the Andreev states in the 4He fluid layers.
