DEFINITION NONPERTURBATIVE AND RELATIVISTIC AMENDMENTS TO HAMILTONIAN INTERACTIONS

Abstract

We propose on of the alternative version of calculation the energy spectrum of the bound state systems with satisfied the relativistic invariance. Our approach is based on the investigation of the asymptotic behaviour of the polarization loop function for scalar charged particles in an external gauge field and we determine the mass spectrum of bound state. The nonperturbative corrections arising due to the relativistic nature of system to the interaction Hamiltonian are determined.
