Abstract: 

Moments of inertia and rotational velocity fields are calculated in the cranking model for the harmonic oscillator and the Nilsson potential for even-even rare earth nuclei. By means of a temperature-averaging procedure these quantities are decomposed into a smooth and a shell-structure-dominated part. The results are in good agreement with the corresponding Strutinsky-averaged results. The velocity fields are analyzed in terms of vector spherical harmonics and compared to rigid flow. The smooth velocity fields reveal rigid flow in the nuclear interior; in the surface region a deviation from rigid flow occurs, giving rise to a backflow in the inner system. The temperature dependence of the smooth moments of inertia is approximated by a quadratic function.
