Abstract.

By assuming that the \( f_0\) and \( a_0^0\) mesons are mixed states of the two-quark-tetraquark, the mixing angle between them is estimated within the QCD sum rules method, and it is obtained that the mixing angle is \( (6.03 \pm 0.08)^\circ\) . Our prediction on the mixing angle can be checked in further experiments which can shed light on choosing the “right” structure of \( f_0\) and \( a_0^0\) mesons.
