Abstract
The influence of a steady heat flow on the superfluid transition temperatureT λ , has been investigated by a differential, high-resolution procedure using the velocity of second sound as a probe of δT λ . No shifts inT λ were detected for heat fluxes Q up to 0.160 W/cm2. For 4.0×10−4<Q<3.5×10−2 W/cm2 we find δT λ ≤1.3(±1.6)×10−4 Q kelvins.
