Krein, G.Thomas, A.Tsushima, K.2006-07-052006-07-051999Nuclear Physics A, 1999; 650(3):313-3250375-9474http://hdl.handle.net/2440/10851The mean field description of nuclear matter in the quark-meson coupling model is improved by the inclusion of exchange contributions (Fock terms). The inclusion of Fock terms allows us to explore the momentum dependence of meson-nucleon vertices and the role of pionic degrees of freedom in matter. It is found that the Fock terms maintain the previous predictions of the model for the in-medium properties of the nucleon and for the nuclear incompressibility. The Fock terms significantly increase the absolute values of the single-particle, four-component scalar and vector potentials, a feature that is relevant for the spin-orbit splitting in finite nuclei. © 1999 Elsevier Science B.V.enCopyright © 1999 Published by Elsevier B.V.Journal article0030004494001999082610.1016/S0375-9474(99)00117-70000802487000052-s2.0-003358338568500Thomas, A.
