The Coefficient of First Viscosity Via Three-Phonon Processes in Bulk Liquid Helium

The contribution of three-phonon processes to the coefficient of first viscosity in bulk liquid helium is evaluated explicitly as a function of temperature, which is shown to have a 1/T dependence. Prepared in cooperation with Korea Univ., Seoul, Dept. of Physics.
