“…3 indicate that further constraints on the type of density dependence might be obtained from the single particle spectra. Proton and neutron single particle energies from DD, SDD and VDD calculations with the Bonn A parameter set are shown for ' 0 in Table III [41].Even if one considers the large uncertainties in the experimental values one is led to the conclusion that rearrangement improves the agreement significantly. On the average, the VDD results are again closest to the data.…”

Density dependent hadron field theory

A fully covariant approach to a density dependent hadron field theory is presented. The relation between in-medium NN interactions and field-theoretical meson-nucleon vertices is discussed. The medium dependence of nuclear interactions is described by a functional dependence of the meson-nucleon vertices on the baryon field operators. As a consequence, the Euler-Lagrange equations lead to baryon rearrangement self-energies which are not obtained when only a parametric dependence of the vertices on the density is assumed. It is shown that the approach is energy-momentum conserving and thermodynamically consistent. Solutions of the field equations are studied in the mean-field approximation. Descriptions of the medium dependence in terms of the baryon scalar and vector density are investigated. Applications to infinite nuclear matter and finite nuclei are discussed. Density dependent coupling constants obtained from Dirac-Brueckner calculations with the Bonn NN potentials are used, Results from Hartree calculations for energy spectra, binding energies, and charge density distributions of ' 0, ' Ca, and Pb are presented. Comparisons to data strongly support the importance of rearrangement in a relativistic density dependent field theory. Most striking is the simultaneous improvement of charge radii, charge densities, and binding energies. The results indicate the appearance of a new "Coester line" in the nuclear matter equation of state.
