Phonon dispersion in liquid He II

Journal Article · · Phys. Rev., B, v. 12, no. 9, pp. 3745-3748
The eigenfunctions of the linearized collision operator for the phonons in superfluid helium are determined numerically. The calculated sound velocity is in quantitative agreement with experimental data in a wide frequency and temperature range if an anomalous dispersion $gamma$=-10$sup 38$ in cgs units is used. (auth)
