We study the radiative decay phi --> pi(0)etagamma within the framework of a phenomenological approach in which the contributions of the rho meson, chiral loop and a(0) meson are considered. We analyse the interference effects between different contributions and utilizing the experimental branching ratio and invariant pi(0)eta mass spectrum for the phi --> pi(0)etagamma decay, we estimate the branching ratio of the phi --> a(0)gamma decay.
