Abstract:

Nuclear matter properties are evaluated using our nonstatic OBEP. The binding energy of nuclear matter is calculated to the first-order reaction matrix G. As the nucleon-nucleon interaction, four kinds of potentials are considered that reproduce approximately equivalent phase shift, but differ from each other in the core potential (static Gaussian or velocity-dependent) and in the retarded effect (included or not).
Our OBEP including retardation gives -12 MeV in binding energy at a saturation density kF=1.5 fm-1. The retarded effect of the OBEP is appreciable on the off-energy-shell G-matrices, and decreases simultaneously 2.0 ∼2.5 MeV in the binding energy and ∼0.05 fm-1 (in Fermi momentum) in the density. The relativistic correction to the Bethe-Goldstone equation tends to increase the binding and the density.
The defect wave function and wound integral for each potential case are examined in detail.
