Abstract

We study the radiative decays omega --> etapi(o)gamma and rho(o) --> etapi(o)gamma within the framework of a phenomenological approach in which the contributions of the intermediate a(o)-meson and intermediate vector meson states are considered. We conclude that although the ao-meson intermediate state amplitude makes a small contribution to omega --> etapi(o)gamma decay, it makes a substantial contribution to rho(o) --> etapi(o)gamma decay.
