Complete Experiments of Pion Photoproduction

Possibilities of the complete experiments of pion photoproduction are discussed. For gamma ray ene\:gy up to 400 MeV measuremensts of the following four independent quantities are complete; two differential cross sections with linearly polarized gamma rays, the polarization of the recoil nucleon and differential cross section on a polarized nucleon target. Use of the deuteron target is emphasized and a formulation is made for the pion photoproduction from deuteron. We propose an alternative experiment with deuteron target in which the effect of the Pauli principle is most appreciable. Kinematics and counting rates in these experiments arediscussed. Rela.ted cross sections and polarizations are calculated by the use of the Chew-Golclberger-Low-Nambu theory.
