The Scattering of Gamma-ray by Nucleon and Nucleon Isobars
Department of Physics, Osaka University
(Received December 9, 1952)
Assuming the nucleon isobar with spin J = 3/2, isotopic spin I = 3/2 and mass M = 1210 Mev, we have studied the scattering of gamma ray by nucleon by the covariant perturbation method. As is expected, the total cross section varies strongly with incident gamma-ray i.e., the correction for Klein-Nishina formula at the threshold energy for meson production is only of about 30 percent, but at the excitation energy of isobar a remarkable resonance scattering is found. The angular distribution has a tendency to become predominant in the forward direction with the increase of incident energy.
