Abstract

We report a series of precision measurements of the temperature variation of the constant volume heat capacity C_v of liquid ⁴He near the lambda transition, in samples covering the complete density range between the saturated vapor and freezing pressures. For He II, our C_v data have a temperature dependence that is close to logarithmic at all densities. For He I, C_v is close to logarithmic only at the lowest densities, and obeys finite power laws at higher densities.
