摘要

In the q(q) quark model, the states π(1300), η(1295) and η(1475) are assigned as the 21S0 meson nonet. The mass of the isodoublet remains interesting and needs further confirmation in experiments. This paper employs the phenomenological trajectory on the (N, M2)-plot and meson-meson mixing methods to calculate the mass of this state,the calculated results are 1341 MeV and 1311.58 ± 59 MeV respectively. These predictions can be compared with experiments in the future.
