Abstract
We report experimental results for the depression of the superfluid transition temperature T(Q) in He4 by a heat current Q. The data were obtained by use of thermometry with a resolution of 10 nK, and cover the range 0.4Q10 W/cm2. They can be represented by 1T(Q)/T(0)=(Q/Q0)x with Q0=568±200 W/cm2 and x=0.813±0.012, and are in good agreement with theoretical predictions.
