KHARKOV DATA ON PION PHOTOPRODUCTION AND Δ + (1232) RESONANCE PARAMETERS

We present the analytic review of π and π mesons photoproduction off the proton target as the only source of information about the ∆(1232) resonance parameters. The review focuses at the estimation of the influence of different contributions to the experimental database on determination of the E2/M1 ratio for γp→∆ transition and the resonance parameters, with discussion of the previous Kharkov results.
