Photoproduction of Neutral Pions at Backward Angles in the Resonance Region and the $\eta$ - Cusp

Inspire Record 140694 DOI 10.17182/hepdata.50217

At the Bonn 2.5 GeV electron synchrotron we have measured the differential cross section of the reaction γp→π0p at a pion CM angle of 170° and at photon energiesKγ between 0.6 and 1.8 GeV. In comparison to previous measurements the accuracy of the data was improved substantially. For the first time in neutral pion photoproduction a cusp structure at the η-threshold has been confirmed [1].

Photoproduction of Neutral Pions in the Region of the Fourth Nucleon Resonance

Althoff, K.H. ; Gies, M. ; Kaul, O. ; et al.
Z.Phys.C 1 (1979) 257, 1979.
Inspire Record 140695 DOI 10.17182/hepdata.50276

We report the measurement of the differential cross section of the reaction γ +p→π0 +p at a photon energy of 1.4 GeV and pion c.m. angles between 60 and 175 degrees. The angular distribution confirms the simple quark model prediction of a pure magnetic excitation of theF37 (1950) resonance.
