摘　　要：In the framework of the relativistic mean field theory combined with the complex momentum representation method,we elucidate the pseudospin symmetry in the single-neutron resonant states and its dependence on the σ,ω,and ρ meson fields.Compared with the effect of theρfield,the τandωfields provide the main contributions to the pseudospin energy and width splitting of the resonant pseudospin doublets.Especially,we compare quantitatively the pseudospin wave functions's plittings in resonant doublets,and investigate their dependencies on different fields of mesons,which is consistent with that of energy and width splittings.Current research is helpful to understand the mechanism and properties of pseudospin symmetry for resonant states.
