Abstract

The masses of the K₁(³P₁) and K₁(¹P₁) are considered in a nonrelativistic constituent quark model, and the absolute value of the K₁(³P₁)-K₁(¹P₁) mixing angle is determined to be about 59.29^∘. Comparison of the theoretical predictions on the strong decay widths of the K₁(1270) and K₁(1400) in the ³P₀ decay model as well as the production ratio of these two states in the τ decay between the available experimental data strongly favors that the K₁(³P₁)-K₁(¹P₁) mixing angle is about +59.29^∘.
