Abstract A C ^(++) code is used to calculate ground state properties of spherical nuclei. The nuclear system is described in the framework of relativistic mean field theory: nucleons are coupled to exchange mesons and photon through an effective Lagrangian. Finite element methods are used in the self-consistent solution of the coupled system of partial differential equations for the nucleons and for the meson fields. Using a formulation based ... Title of program: Catalogue Id: ADFG_v1_0 Nature of problem The ground-state of a spherical nucleus is described in the framework of relativistic mean-field theory. The model explicitly includes mesonic degrees of freedom and describes the nucleons as Dirac particles. Nucleons interact in a relativistic covariant manner through the exchange of virtual mesons: the isoscalar scalar sigma-meson, the isoscalar vector omega-meson and the isovector vector rho-meson. The model is based on the one boson exchange description of the nucleon- nucleon interaction.
