    "abstract": "A key point of Dirac Brueckner Hartree Fock calculations for nuclear matter\nis to decompose the self energy of the nucleons into Lorentz scalar and vector\ncomponents. A new method is introduced for this decomposition. It is based on\nthe dependence of the single-particle energy on the small component in the\nDirac spinors used to calculate the matrix elements of the underlying NN\ninteraction. The resulting Dirac components of the self-energy depend on the\nmomentum of the nucleons. At densities around and below the nuclear matter\nsaturation density this momentum dependence is dominated by the non-locality of\nthe Brueckner G matrix. At higher densities these correlation effects are\nsuppressed and the momentum dependence due to the Fock exchange terms is\ngetting more important. Differences between symmetric nuclear matter and\nneutron matter are discussed. Various versions of the Bonn potential are\nconsidered.",
