Assignment of Isodoublet of 2³S₁ Meson Nonet

Inserting the masses of some states, which have been established in the
experiments or the theory of lattice QCD, we investigate the mass of the
isodoublet of the 2³S₁ meson nonet. The agreement results, 1567±22.6MeV and 1576.8MeV, are given by two different approaches. We suggest that the assignment of 2³S₁ meson nonet should be re-examined in future experiments.
