摘要：

The large s, small t pion photoproduction data and the corresponding continuous moment sum rules are fitted with evasive Regge poles and associated Regge cuts, instead of the commonly accepted pion conspiracy. The FESR actually yield the real parts of the photoproduction amplitudes, essentially independent of the model. A further assumption permits the prediction (in good agreement with existing data) of high energy cross sections directly from the FESR, without commitment to any particular model. © 1969.
