Extraction of nuclear matter properties from nuclear masses by a model of equation of state

The extraction of nuclear matter properties from measured nuclear masses is investigated in the energy density functional formalism of nuclei. It is shown that the volume energy a1 and the nuclear incompressibility K0 depend essentially on μnN + μpZ − 2EN , whereas the symmetry energy J and the density symmetry coefficient L as well as symmetry incompressibility Ks depend essentially on μn − μp, where μp = μp − ∂EC/∂Z, μn and μp are the neutron and proton chemical potentials respectively, EN the nuclear energy, and EC the Coulomb energy. The obtained symmetry energy is J = 28.5MeV , while other coefficients are uncertain within ranges depending on the model of nuclear equation of state. PACS: 21.65.+f, 24.30.Cz
