摘      要：The g factors and spectroscopic quadrupole moments of low-lying excited states 2+1,…,81+ in 24Mg are studied in a covariant density functional *** wave functions are constructed by configuration mixing of axially deformed mean-field states projected on good angular *** mean-field states are obtained from the constraint relativistic point-coupling model plus BCS calculations using the PC-F1 parametrization for the particle-hole channel and a density-independent delta-force for the particle-particle *** available experimental g factor and spectroscopic quadrupole moment of 21+ state are reproduced quite *** angular momentum dependence of g factors and spectroscopic quadrupole moments,as well as the effects of pairing correlations are investigated.
