The Low-Energy Compton Scattering on the Basis of the Effective Lagrangian in the Gauge Invariance Approach for Spin 1/2 Particle.
N. V. Maksimenko and S. A. Lukashevich

Within the limits of the relativistic gauge-invariant approach we obtain the Lagrangian of electromagnetic field interaction with a structural spin 1/2 particle . The Lagrangian allows by the covariant method to calculate the contribution of polarizabilities both to the amplitude and to the cross sections of two-photon's processes.
Key words: covariant Lagrangian, differential cross section, sum rules
