Abstract

We have measured the frequency shift of the counterflow-induced peak in the NMR spectrum of the flare-out texture in rotating ³He in a vortex-free state. From a comparison with the calculated shifts, the temperature dependence of the dipolar velocity at P=5.0 and 29.3 bar has been deduced. Our results are in good agreement with theoretical predictions.
