In this paper, exclusive decays and are analyzed. It is shown that contributions of the excited mesons should be taken into account to describe these decays. It is also shown that, unlike the corresponding lepton decays, peaks in distributions caused by these resonances are clearly seen and can be easily separated. Theoretical predictions for the branching fractions of the reactions and distributions are also presented.
