Abstract
Preliminary data for the heat capacity of 3He in 3He-4He mixture films on a Nuclepore substrate are reported over the temperature range 90≤T≤165 mK, for 3He coverages between 0.05 and 1.7 bulk-density atomic layers, and a 4He film thickness of 4.33 bulk-density atomic layers. In this two-dimensional Fermi liquid system, a step structure appears in the specific heat as a function of 3He coverage, similar to the step previously observed in the magnetization.

A reasonable estimate of the empty-cell background derived from linear extrap-olation to zero coverage of the measured total specific heats of the two lowest 3He coverages has been applied to the data.
The thickness scale presented here has been normalized to that used in the maganitzation experiments by use of the positions of the beginning of the filling of the first and second excited states.
