Ripplon damping in superfluid 4He at low temperatures

  • 1. Department of Physics, Clark University, Worcester, Massachusetts 01610

Description

The damping coefficient (imaginary part of the frequency) of ripplons in superfluid 4He at low temperatures T is found to be tau-1/sub q/ = 0.376 (h/rho0) (k/sub B/T/hγ)/sup 10/3/ due to processes in which the acoustic ripplon is absorbed by a thermal ripplon. the range of wave vectors for which a direct experimental observation of the ripplon might be possible is discussed
