Reflection asymmetric relativistic mean field approach and its application to the octupole deformed nucleus ${}^{226}$Ra

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-center harmonic-oscillator potential. The efficiency and reliability of the RAS-RMF approach are demonstrated in its application to the well-known octupole deformed nucleus ${}^{226}$Ra and the available data, including the binding energy and the deformation parameters, are well reproduced.
