Measurement of total photonuclear cross sections in the Δ-resonance region

Abstract Double differential cross sections for the photoemission of protons and charged pion photoproduction were investigated for a number of target nuclei (He, Be, C, O, Al, Ti, Cu, Sn, Pb) using the tagged bremsstrahlung beam at the Bonn 500 MeV-Synchrotron in the photon range k = (215–386)MeV. On the basis of these experimental results the total hadronic cross section was determined.
