Abstract

The specific heat of liquid He3/He4 mixtures has been measured at saturated vapor pressure for three values of the He3 mole fraction x near the junction of the lambda and phase-separation curves. The specific heat at the lambda peak appears to be finite, continuous, and cusped. Both the lambda peak and the anomaly in the specific heat as the system goes from the two-liquid-phase region to the one-liquid-phase region tend to disappear as the junction of phase boundaries is approached.
