We estimate the rates for radiative transitions of the lightest scalar mesons f_0(980) and a_0(980) to the vector mesons rho and omega. We argue that measurements of the radiative decays of those scalar mesons can provide important new information on their structure., Comment: 20 pages, 5 figures; appendix added, to be published in Phys. Rev. C
