Abstract
The radiative decays and with and are calculated within the framework of the Linear Sigma Model. Current experimental data on the and branching ratios and the ratio are satisfactorily accommodated in our approach. We also estimate the decay widths of the transitions. All the processes considered are of interest for ongoing experimental programs in Frascati, J\"ulich and Novosibirsk.
