Non-polarizing two-atom interaction potential in the liquid He-4
D. B. Baranov, V. S. Yarunin, A. I. Kirillov
A formula for potential U of the He-4--He-4 interaction in the liquid state is obtained by the direct electromagnetic computation as a function of the interatomic distance R. The p…

Two-atomic potential and distortion of excitation spectrum of liquid He-4 by admixture of He-3
D. B. Baranov, V. S. Yarunin, A. I. Kirillov
The new interatomic potential g(r), providing the tunnelling of atoms, is suggested for calculating HFB phonon-roton spectrum E(p) of liquid He-4. The tunnelling enables the calcul…
