π0-meson pole in γ p scattering and proton polarizability
Baranov P.S., Fil'kov L.V., Shtarkov L.N.
It is shown that allowance for the 7T°-meson pole is essential when the proton polarizability is determined from experiments on у ρ scattering. The sign of the я-0—»2γ decay amplitude is obtained from experiments on yp scattering in the range 80-110 MeV, namely g wNNF π<0.
