Abstract
A new potential, which accounts for roton-roton interaction is proposed. Using this potential without any adjustable parameters, the calculated roton-roton contribution to the viscosity of He II in the temperature range between 1.35 °K and 1.9 °K is found to be in qualitative agreement with the experimental value. © 1969 Società Italiana di Fisica.File in questo prodotto:
