On the macroscopic limit of nuclear collective motion and its relation   to chaotic behavior
  In this note we concentrate on slow collective motion of isoscalar type at small but finite excitations, as given in nuclear fission, for instance. We report on microscopic results of transport coefficients, review how they depend on temperature and address the interplay of one and two body viscosity. We examine how transport properties might be influenced by chaotic behavior of nucleonic dynamics.
