Abstract

A 3He film formed in quite narrow pores is one of the possible model systems for a one-dimensional Fermi fluid. Here we report our new heat capacity resugts of 3He and 4He film adsorbed in a straight pore 28 Å in diameter down to 5 mK. The coverage and temperature dependence of the heat capacity indicates that a fluid phase appears between the second layer promotion and the complete filling of the pores. Since the heat capacity of 3He adsorbed on the bare substrate shows a large upturn due to the nuclear heat capacity of the localized 3He, it is difficugt to observe the true heat capacity of the fluid phase. By replacing the localized 3He, we can successfully suppress the upturn and observe the true heat capacity of the fluid phase.
