英文摘要	The contribution of the resonant continuum to pairing correlations is properly treated in the RMF + BCS approximation with a constant pairing strength. The results show that the contribution of the proper treatment of the resonant continuum to pairing correlations for those nuclei close to neutron drip line is important. The quasiparticle relativistic random phase approximation is applied to investigate the collective excitations of the open shell nucleus. The numerical calculations are performed in the case of various isoscalar giant resonances of nucleus Sn-120. The calculated results show that the quasiparticle relativistic random phase approximation approach could satisfactorily reproduce the experimental data of the energies of low-lying states.
