Özet

We study the radiative decay p(0) --> pi (0)pi (0)gamma within the framework of a phenomenological approach in which the contributions of sigma -meson and omega -meson intermediate states and of the pion-loops are considered. We conclude that the sigma -meson amplitude makes a substantial contribution. (C) 2001 Elsevier Science B.V. All rights reserved.
