摘要： This paper discusses the masses and possible members of 21S0 and 23S1 meson multiplets in the framework of meson--meson mixing and Regge phenomenology. For the 21S0 meson nonet, K*(1460) may be the observed state of the 21S0 isodoublet with a mass of 1400~MeV and the mass of ω(1420) is 1412~MeV. For the 23S1 meson nonet, K*(1410) seems too light to be the 23S1 n\overline{s} member. The fact that the agreement between the present findings and those given by experiments and other different approaches is satisfactory implies that the assignments in this paper may be reasonable.

Abstract: This paper discusses the masses and possible members of $2^1S_0$ and $2^3S_1$ meson multiplets in the framework of meson--meson mixing and Regge phenomenology. For the $2^1S_0$ meson nonet, $K^*(1460)$ may be the observed  state of the $2^1S_0$ isodoublet with a mass of 1400~MeV and the mass of $\omega(1420)$ is 1412 MeV. For the $2^3S_1$ meson nonet, $K^*(1410)$ seems too light to be the $2^3S_1$ $n\overline{s}$ member. The fact that the  agreement between the present findings and those given by experiments and other different approaches is satisfactory implies that the assignments in this paper may be reasonable.
