Abstract:
The effective Lagrangians and amplitudes of Compton scattering on pion and nucleon with the account of electric and magnetic polarizabilities are obtained on the basis of the theoretical-field approach and solutions of electrodynamic equations by means of Green functions covariant method. Calculations of magnetic and electric quasi-static polarizabilities of spinor particle were evaluated on the basis of matrix elements calculation for Compton scattering amplitudes.
Keywords:polarizability, Lagrangian, Compton scattering, Green function.
