Özet

We study the radiative rho(0)-->pi(+)pi(-)gamma and rho(0)-->pi(0)pi(0)gamma decays and we calculate their branching ratios using a phenomenological approach by adding to the amplitude calculated within the framework of chiral perturbation theory and vector meson dominance the amplitude of sigma-meson intermediate state. Our results for the branching ratios are in good agreement with the experimental values.
