Solution of Relativistic Two-Particle Equations with Arbitrary Orbital Angular Momentum

Abstract

Bound states of relativistic systems of two particles are considered in the special case of an interaction operator which admits reduction of partial integral equations to differential equations directly in the momentum representation. Exact analytical solutions of these equations are obtained for some values of the energy (mass) of a system of two particles. Equations with other energies are solved numerically. Dependences of the mass spectra of two-particle systems and their wave functions on the parameters are found.
