Abstract
The relativistic structure of the self-energy of a nucleon in nuclear matter is investigated including the imaginary and real components whi ch arise from the terms of first and second order in the NN interactio n. A parameterized form of the Brueckner G-matrix is used for the NN i nteraction. The effects of the terms beyond the DBHF approximation on quasiparticle energies and the optical potential for nucleon-nucleus s cattering are discussed. (C) 1998 Elsevier Science B.V.
