Özet

We consider the two point correlation function of a scalar current in the QCD sum rule approach to estimate the overlap amplitude of the a(o)-meson. We then employ QCD sum rules to calculate the coupling constants g(omegaaogamma) and g(rhoaogamma) by studying the three point a(o)omegagamma- and a(o)rhogamma-correlation functions.
