On the Mixing of the D-wave Strange Mesons
Abstract：In the presence of th π2 （1 670）, η2 （1 870）and η2 （1 645） being the members of the1^1 D2meson nonet, based on the mass-squared matrix and the nonrelativistie constituent quark model, the mass of the isodoublet K（^1D2） is estimated with a good agreement , Further, with the help of the above value, it is suggested that the mixing angle between K（^1D2） and K（^3D2） is about 0 degrees. Then, some decay widths of K2 （1 770） and K2 （1 820） are estimated by the^3 P0 decay model. The mixing angle beween them is difficult to confirm resoting to compare the result of^3 P0 decay model with the PDG datas.
