Özet

In quark model, the strange axial vector mesons K-1(1270) and K-1(1400) are defined as the mixtures of orbital angular momentum states K-1A and K-1B. In this work, by using the orthogonality of the mass eigenstates, we have estimated the K-1(1270; 1400) mixing angle theta(K1), where we have found that theta(K1) similar or equal to -(39 +/- 4)degrees.
