Dynamical moment of inertia and quadrupole vibrations in rotating nuclei


Dynamical moment of inertia and quadrupole vibrations in rotating nuclei

Nazmitdinov, R. G.; Almehed, D.; Dönau, F.

The contribution of quantum shape fluctuations to inertial properties of rotating nuclei has been analysed within the self-consistent one-dimensional cranking oscillator model. It is numerically proven that for even-even nuclei the dynamical moment of inertia calculated in mean field approximation in the intrinsic frame is equivalent to the
Thouless-Valatin moment of inertia. If the contribution of the quantum fluctuations
to the total energy is taken into account, the dynamical moment of inertia differs from the Thouless-Valatin value.
