Phase Transition Face-Centered Cubic Crystal—Homogeneous Phase in Helium

In the study, the characteristics of the phase transition from a face-centered cubic crystal to a homogeneous phase in helium were calculated based on the correlation cell–cluster extension. A comparison of theoretical data with experimental data was conducted, and good agreement was obtained. The use of data on phase transitions in helium for estimating the thermodynamic characteristics of the phase transition in a quantum system of hard spheres is discussed.
