Abstract: Relativistic Hartree-Fock (RHF) theory has been adopted to describe properties of exotic nuclei. In order to investigate the contribution of Fock term and isovector mesons to the properties of exotic nuclei and to avoid effective interaction which is not unique, the density dependent relativistic Hartree (RDH) and relativistic Hartree-Fock(RDHF) theories with parameter free have been extended to describe the properties of exotic nuclei. The properties of Calcium isotope chain are calculated in the RDH and RDHF approaches, and the contribution of the Fock term and isovector mesons to the properties have been investigated particularly. It turns out that the influence of the Fock term and isovector mesons on the properties of neutron very rich nuclei, such as binding energies, RMS of neutron radius and distribution of neutron density, is very different from those of stable nuclei. We also briefly discuss importance of study on the properties of nuclei near drip line and the theoretical model used in this paper.
