Scientific paper

The coupling constants of α0 --> ωγ, f0 --> ωγ, α0 --> ργ, and f0 --> ργ are calculated using 3-point QCD sum rules. We estimate the coupling constants gα0ωγ, gf0ωγ, gα0ργ and gf0ργ which are an essential ingredient in the analysis of physical processes involving isoscalar f0(980) and isovector α0(980) mesons.
