Form Factor for a System of the Two Fermions an Equal Masses in the Relativistic Quasipotential Approach

Abstract

The new relativistic form factor of the two relativistic with equal masses fermions bound state for the scalar and the vector-current cases are obtained. Consideration is conducted within the framework of relativistic quasipotential approach on the basis of covariant Hamiltonian formulation of quantum field theory by transition to the three-dimensional relativistic configurational representation in the case of two relativistic spin particles with equal masses.
