Abstract

The configuration-fixed deformation constrained relativistic mean field approach with time-odd component has been applied to investigate the ground state properties of ³³Mg with effective interaction PK1. The ground state of ³³Mg has been found to be prolate deformed, β ₂=0.23, with the odd neutron in 1/2[330] orbital and the energy -251.85 MeV which is close to the data -252.06 MeV. The magnetic moment -0.9134 μ _N is obtained with the effective electromagnetic current which well reproduces the data -0.7456 μ _N self-consistently without introducing any parameter. The energy splittings of time reversal conjugate states, the neutron current, the energy contribution from the nuclear magnetic potential, and the effect of core polarization are discussed in detail.
