Description

The equation of state of neutron-rich matter is studied in the framework of the Brueckner-Bethe-Goldstone approach. In addition to the bare two-body force a microscopic three-body force, based on the meson exchange model, has been introduced that largely improves the saturation properties of nuclear matter. Systematic calculations for several densities and isospin asymmetries show that the symmetry energy drives the isospin effects up to large densities and asymmetries. The density dependence of the symmetry energy is also discussed and compared with other predictions. (author)
