摘要
Mixing between the 2^3S1 and 1^3D1Ds is studied within the 3P0 model. If mixing between these two 1 states exists, Ds1^＊ （2700） ± and DsJ^＊（2860）± could be interpreted as the two orthogonal mixed states with mixing angle θ ≈-80 °in the case of a special β for each meson. However, in the case of a universal β for all mesons, D_（s1）~＊（2700） ± could be interpreted as the mixed state of 23S1 and 13D1 with mixing angle 12° θ 21° but D_（sJ）~＊（2860）± seems difficult to interpret as the orthogonal partner of D（s1）~＊（2700）±.
