Theory of Heat Capacity of Liquid Helium-4 for Temperatures above the Critical Point

We analyze numerically the behavior of the heat capacity of liquid 4He for the entire temperature range with the corresponding formula for the internal energy obtained in Ref. [I.O. Vakarchuk, R.O. Prytula, A.A. Rovenchak, J. Phys. Stud. 11, 259 (2007)] combined with a simple calculation of the effe...

Zusammenfassung:We analyze numerically the behavior of the heat capacity of liquid 4He for the entire temperature range with the corresponding formula for the internal energy obtained in Ref. [I.O. Vakarchuk, R.O. Prytula, A.A. Rovenchak, J. Phys. Stud. 11, 259 (2007)] combined with a simple calculation of the effective mass of interacting Bose particles. The results agree quite well with experimental data.
