Abstract A reflection asymmetric relativistic mean field (RAS-RMF) approach is developed by expanding the equations of motion for both the nucleons and
the mesons on the eigenfunctions of the two-centre harmonic-oscillator
potential. The efficiency and reliability of the RAS-RMF approach are demonstrated in its application to the well-known octupole deformed
nucleus 226Ra and the available data, including the binding energy and the deformation parameters, are well reproduced.
