Nuclear fluid dynamics

For energies where the mean free nucleon path is comparable to the nuclear size, there is no fast local relaxation in nuclear collective motion. Therefore, in a fluid-dynamical approach, the intrinsic energy-density functional must take the distortion of the local Fermi surface into account. This can be achieved by a dynamical Thomas Fermi method which leads to additional restoring forces for the collective modes, except for the casesL=0 andL=1 where usual hydrodynamics is sufficient.
