ANOMALOUS PHONON-SPECTRA IN BULK AND THIN LIQUID HE-II .2. APPLICATIONS TO KINETIC COEFFICIENTS

Using the zero-temperature and temperature-dependent elementary excita tion spectra obtained in the previous paper (hereafter, referred to Pa per I), we evaluate the temperature dependence of kinetic coefficients -thermal conductivity, first and second viscosity-in pure liquid He II and dilute He-3-He-4 mixtures. In all the coefficients, three phonon processes, which can be possible only in the anomalous phonon spectrum , are the important phonon processes at low temperatures and pressures . By considering these processes explicitly, we obtain the considerabl e improvements for all the coefficients.
