Abstract

The results of the self-consistent phonon theory developed by Plakida and Siklos with the generalized form of the Lennard- Jones (n,m) model of interatomic interactions in the lattice of bcc ³He and ideally hcp ⁴He are given. Theoretical values for the pressure and temperature variations of the dynamic and thermodynamic function of strongly anharmonic crystals of helium are compared with experimental data.
