Photoproduction of Negative Pions from Carbon in the Energy Range between 510 MeV and 750 MeV

The cross section of the photoproduction of pions from carbon at 41° in the laboratory system and in the incident energy region from 510 MeV to 750 MeV is measured by a magnetic spectrometer for pions and counter hodoscopes for recoil protons in coincidence with pions. A tagged photon beam is used. The results which show the production of pions from the quasi free nucleons inside the nucleus are analyzed in terms of the distorted wave impulse approximation.
