Constraining the density dependence of the symmetry energy in the nuclear equation of state using heavy ion beams Academic Article

abstract

• The density dependence of the symmetry energy in the equation of state of asymmetric nuclear matter (N/Z > 1) is important for understanding the structure of systems as diverse as the atomic nuclei and neutron stars. Due to a lack of understanding of the basic nucleon-nucleon interaction for matter that is highly asymmetric and at non-normal nuclear density, this very important quantity has remained largely unconstrained. Recent studies using beams from the Cyclotron Institute of Texas A&M University constrain the density dependence of the symmetry energy. A dependence of the form Esym() = C(/o), where C = 31.6 MeV and = 0.69, is obtained. Their implications to both astrophysical and nuclear physics studies are discussed. 2007 Elsevier B.V.
