Abstract.

The masses of K 1(3 P 1) and K 1(1 P 1) are considered in a nonrelativistic constituent quark model, and the absolute value of the K 1(3 P 1)- K 1(1 P 1) mixing angle is determined to be about 59.29°. The comparison of the theoretical predictions on the strong decay widths of K 1(1270) and K 1(1400) in the 3 P 0 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 K 1(3 P 1)- K 1(1 P 1) mixing angle is about +59.29°.
