In a recent work we have shown how the reaction matrices of the relativistic-Brueckner-Hartree-Fock theory can be well approximated in a simple model. In that model we could reproduce various matrix elements of the relativistic-Brueckner-Hartree-Fock reaction matrices in the Born approximation, if we added a number of pseudoparticles to the ''mesons'' used to construct one-boson-exchange models of the nuclear force. Here we present nuclear matter saturation curves, obtained using our pseudoparticle method, for two one-boson-exchange potentials. Our simple model reproduces the saturation curves calculated with the full relativistic-Brueckner-Hartree-Fock theory quite well. Within the context of the pseudoparticle approximation to the full relativistic-Brueckner-Hartree-Fock theory, one obtains reasonable values for the incompressibility parameter. (These values are quite similar to those obtained earlier using the full relativistic-Brueckner-Hartree-Fock analysis.)
