Partial widths a₀(980)toγγ, f₀(980)toγγ and qbar q-classification of the lightest scalar mesons

We calculate partial widths for the decays a_0(980)\to\gamma\gamma and f_0(980)\to\gamma\gamma under the assumption that a_0(980) and f_0(980) are members of the basic 1^3P_0 q\bar q nonet. The results are in a reasonable agreement with data thus giving an argument for a q\bar q origin of these mesons. We also calculate the \gamma\gamma partial widths for the other scalar mesons, members of the 2^3P_0 q\bar q nonet.
