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 s hown that the volume energy a, and the nuclear incompressibility K-0 depend essentially on mu N-n + <(<mu>)over bar>(p)Z - 2E(N), whereas the symmetry energy J and the density symmetry coefficient L as well as symmetry incomp ressibility K-s depend essentially on mu (n) - <(<mu>)over bar>(p), where < (<mu>)over bar>(p) = mu (p) - partial derivativeE(C)/partial derivativeZ, m u (n) and mu (p) are the neutron and proton chemical potentials respectivel y, EN the nuclear energy, and EC the Coulomb energy. The obtained symmetry energy is J = 28.5 MeV, while other coefficients are uncertain within range s depending on the model of nuclear equation of state.
