Abstract

Total cross sections for π0 photoproduction on Be, C, Al, Cu, Sn and Pb have been measured in the photon energy range k = 220–450 MeV using the tagged photon beam of the Bonn 500 MeV synchrotron. The data show a broad maximum around k = 350 MeV. The A-dependence can be described by σAA0.66. The results are compared to charged pion production and to total hadronic cross sections.
