Abstract
Using a covariant diagram technique and the concept of a nucleus as an
elementary particle we calculated differential cross-sections for two-particle
photodisintegration reactions of the He-4. The only functional parameter was
the vertex structure function, which described the "collapse" of a He-4 nucleus
and the nucleon remnants. The interaction of a real photon was determined by
the value of particles charge, since the electromagnetic form factors were
calculated in the photon point. The inseparability property of the electric
charge from the particle mass allowed us to match the energy-momentum and
charge conservation laws in the interaction. Therefore, the requirement of
gauge symmetry was immediately satisfied. The covariant amplitude of the
process equaled to the sum of pole diagrams and regular part.
