| 摘 要： | In the qq quark model, the states π2（1670） and η2（1645） are assigned as the I1D2 meson nonet. The partner of state η2（1645） needs further confirmation in the experiments. We employ the meson-meson mixing and the Regge trajectory methods to calculate the mass of the partner of state η2 （1645） to be 1879.8 MeV and 1863 ± 24 MeV respectively. We also calculate the strong decay width in the 3po decay model. These predictions can be compared with experiments in the future.
