Abstract
We present a Fortran program for the calculation of the ground state p roperties of axially deformed even-even nuclei in the framework of Rel ativistic Mean Field Theory (RMF). In this approach a set of coupled p artial differentials has to be solved self-consistently: the Dirac equ ation for the nucleons moving in self-consistent fields and the Klein- Gordon equations for the meson fields and the electromagnetic field, w hose sources are scalar and vector densities determined of the nucleon s. For this purpose the Dirac spinors as well as the meson fields are expanded in terms of anisotropic oscillator wave functions in cylindri cal coordinates. This requires a matrix diagonalization for the soluti on of the Dirac equations and the solution of an inhomogeneous matrix equation for the meson fields. For the determination of the Coulomb fi eld the Greens function method is used. (C) 1997 Elsevier Science B.V.
