  "abstract": "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 calculations to reproduce the experimental dependence of shifts E(p) on pressure P induced by He-3 admixture in the constant total density and volume.",
