Abstract

The experimental branching ratio for the radiative decay rho (0)-pi (+) + pi (-) + gamma is used to estimate the coupling constant g(rho sigma gamma) for a set of values of sigma -meson parameters M-sigma and Gamma (sigma). Our results are quite different than the values of this constant used in the literature.
