Specific heat measurements have been made under pressure on a 5% 3He-4He solution between 10 and 93 mK, yielding values for the specific heat mass, m*, of 2.45 m3, 2.74 m3, and 3.07 m3 at pressures of 0, 10, and 20 atm, respectively; corresponding values of the zero-concentration effective mass m0 are 2.38 m3, 2.64 m3, and 2.90 m3 for the above pressures. Measurements were also made on a 3% solution. Above 35 mK, all the measurements show deviations from a free-Fermi-gas behavior.
