The ground state properties and the shape evolution of even-even Xe, Ba and Ce isotopes were investigated by the Reflection Asymmetric Relativistic Mean Field ( RAS-RMF ) theory. Calculations showed that the RAS-RMF theory presented a good description on the properties of ground states for the consideration of reflecting asymmetric degree of freedom. The calculated binding energy agreed with the experimental data well. The shape evolution of even-even Xe, Ba and Ce isotopes were clearly demonstrated by the deformation parameters and matter density distributions. The results showed that octupole deformation had a significant influence on the ground state properties of nuclei, in which reflection asymmetric degree of freedom played an important role.
