The temperature dependence of the mutual friction force between the normal and superfluid parts of rotating superfluid helium in the critical region near the lambda point is explained on the basis of the hypothesis of dynamic scale invariance. It is shown that the coefficients B and B' in the friction force increase like (..delta..T)/sup() -2-alpha/6/, where ..cap alpha.. is the critical exponent of the heat capacity; this agrees with the experimental data.
