We study the omega and p decays into pi(0)eta gamma using phenomenological approach by adding to the amplitude calculated with in the framework of VMD, chiral loop, a(0)-meson intermediate state and p-omega-mixing. a(0)-meson intermediate state amplitude makes a small contribution for two decays when considering to proceed by a two step mechanism.
