Collision times in a viscoelastic description of nuclei with a diffuse-surface nuclear density

We investigate the fluiddynamical description of nuclear motion induced by the variational procedure in the presence of one- and two-body dissipation. The equation of motion for the scaling field is established for an abnormal parity mode in a nucleus with a Wood-Saxon density. The local relaxation...
