Abstract  Energy in nuclear matter is, in practice, completely characterized at different densities and asymmetries, when the density dependencies of symmetry energy and of energy of symmetric matter are specified. The density dependence of the symmetry energy at subnormal densities produces mass dependence of nuclear symmetry coefficient and, thus, can be constrained by that latter dependence. We deduce values of the mass dependent symmetry coefficients, by using excitation energies to isobaric analog states. The coefficient systematic, for intermediate and high masses, is well described in terms of the symmetry coefficient values of aa V=(31.533.5)MeV for the volume coefficient and aa S=(912)MeV for the surface coefficient. These two further correspond to the parameter values describing density dependence of symmetry energy, of L∼95MeV and Ksym∼25MeV. © 2007 American Institute of Physics.
