Abstract
By assuming that the and mesons are mixed states of the two-quark - tetraquark, the mixing angle between them is estimated within QCD sum rules method, and it is obtained that the mixing angle is . Our prediction on mixing angle can be checked in further experiments which can shed light on choosing the "right" structure of and mesons.
