Abstract

We estimate the rates for radiative transitions of the lightest scalar mesons ${f}_{0}(980)$ and ${a}_{0}(980)$ to the vector mesons \ensuremath{\rho} and \ensuremath{\omega}. We argue that measurements of the radiative decays of those scalar mesons can provide important new information on their structure.
