· Nuovo Cimento (Italy) Divided into Nuovo Cimento A and Nuovo Cimento B
An investigation is made into the form of the isoscalar amplitudes for meson photoproduction on nucleons, using the Mandelstam technique, for energies up to 250 Mev. The bipion'' approximation to the pion-pion interaction is used, and, in the photoproduction channel, an intermediate I = 1/2 = J pion- nucleon state is considered. The results agree with the experimental values of d sigma /sup -/ sigma /sup +/, giving strong evidence for the existence of the pion- pion resonance. An estimate of the coupling constant'' for the process gamma + pi yields pi + pi is hence obtained. (auth)
