Abstract
The angular distributions and the polarizations of recoil nucleons for the meson-nucleon scattering as well as for the photomeson production are studied from the kinematical point of view. Similar to the case of meson-nucleon scattering, as given in our previous papers, there exists a simple symmetry property also in the photomeson production. The angular distribution is invariant under the simultaneous interchange of the reaction amplitudes of electric and magnetic radiations with the same multipole order and the same total angular momentum. This interchange upsets the sense of the polarization of recoil nucleons. For practical purposes the tables of the angular distributions and the polarizations are given for J’s up to 3/2.
