【 摘 要 】

The specific heat and susceptibility data for He-3 on Grafoil are analyzed in the framework of the Landau Fermi-liquid theory. The data suggest that the dominant interaction between He-3 quasiparticles is an attraction in the p-wave channel. We have calculated explicitly the superfluid transition temperature in a two-dimensional Fermi gas and found that the prefactor in T(c) is very small (approximately 10(-2)-10(-3) depending on the form of the potential). For moderate areal densities of He-3, T(c) is estimated to be on the scale of several millikelvin. The relevance of these results to the change in the temperature behavior of the specific heat observed below T(k) = 3.2 mK is discussed.
