Abstract
The angular distribution of positive pion in photoproduction is analysed in the following form of cross section, θcm, and E is calculated unambiguously from the retardation diagram. The four coefficients A, B, C and D are determined with a least square fit to almost all the data available at present for the lab. photon energy Eγ = 180 ∼ 500 MeV. There are compared with Chew, Goldberger, Low and Nambu's theory with Ball's correction to the pion-pion interaction.Keywords
