Zusammenfassung

Mit einem magnetischen Spektrometer wurde am Bonner 500 MeV-Elektronen-Synchrotron die Reaktionγ+p→π ++n für Photonenenergien zwischen 200 und 450 MeV untersucht. Es wurden Anregungskurven für die Laborwinkel 30°, 40°, 60°, 90°, 120°, 150° und 160° gemessen. Die hieraus gewonnenen Winkelverteilungen des differentiellen Wirkungsquerschnittes im Schwerpunktsystem werden mit Messungen anderer Autoren verglichen.

We are grateful to Dr.Lublow and Mr.Stoss for help with the calculations of theπ-μ-decay corrections. We wish to thank Mr.Schneider, Haas andKÜfner for operating the Synchrotron, Mr.Finken andPeschel for constructing parts of the apparatus. Helpful discussions with ProfessorEhrenberg, Dr.Lübelsmeyer and Dr.Freytag are greatfully acknowledged. One of us (K. A.) is indepted to the members of the Caltech Synchrotron Laboratory in particular to ProfessorWalker for his advice and many helpful discussions during a stay at the Caltech Laboratory.
