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 $E_{sym}(\rho )$ lead to significantly different predictions on several $E_{sym}(\rho )$-sensitive experimental observables. The momentum-dependence of the symmetry potential is thus critically important for investigating accurately the equation of state ($\mathrm{EOS}$) and novel properties of dense neutron-rich matter at RIA.
