Özet
The coupling constant of a(0)->rho gamma and f(0)->rho gamma decays are calculated using 3-point QCD sum rules. We estimate the coupling constant g(a0)rho gamma and g(f0)rho gamma which are an essential ingredient in the analysis of physical processes involving isoscalar f(0)(980) and isovector a(0)(980) mesons.
