Abstract
G-matrix elements for finite nuclei are calculated using effective masses for mesons and nucleons at finite density, i.e., those in nuclear medium. We find that the central G-matrix elements are very sensitive to masses of the sigma and omega. By decreasing the mass of the rho, the LS matrix elements are generally enhanced, while the tensor matrix elements are suppressed. A uniform decrease in various masses yields G-matrix elements which are rather consistent with empirical matrix elements obtained by Brown, Richter, Julies and Wildenthal.
