Abstract
We have measured the critical heat current in thermal counterflow in He II as a function of temperature. The results are analyzed in terms of a slightly modified Vinen theory. The agreement between theory and experiment is excellent, providing an independent determination of the parameters of the theory, as well as one of the few examples of a successful theory of critical-velocity phenomena in liquid He II.Keywords
