Skyrme tensor force in heavy ion collisions

NUCLEAR REACTIONS ¹⁶O(¹⁶O, X), E(cm)=100 MeV; calculated contributions from terms involving time-odd densities and currents to the total energy as the sum of isoscalar and isovector contributions, energy contributions from (pseudo)scalar-, vector- and (pseudo)tensor-decomposed form of spin-current tensor J. Symmetry-unrestricted Time-dependent Hartree-Fock (TDHF) energy density functional calculations with full version of Skyrme force, including terms arising only from the Skyrme tensor force. Discussed role of Skyrme tensor force in dynamic processes in nuclei.
