Relaxation caused by one phonon decay into three in superfluid helium
The analytical relation for the rate of one phonon decay into three is obtained. Starting from the relation obtained, the rate of spontaneous decay in the first order of perturbation theory is found. It is shown, that processes of one phonon decay into three provide a fast establishment of equilibri...
