Momentum dependence of the symmetry potential and nuclear reactions induced by neutron-rich nuclei at RIA
Abstract
Effects of the momentum-dependence of the symmetry potential in nuclear reactions induced by neutron-rich nuclei at RIA energies are studied using an isospin- and momentum-dependent transport model. It is found that symmetry potentials with and without the momentum-dependence but corresponding to the same density-dependent symmetry energy

lead to significantly different predictions on several

) and novel properties of dense neutron-rich matter at RIA.
