The present article discuses the problems of relativistic invariance and commutation relations at unitary quantum theory. The scalar analogue of the main (principal) equation of the unitary quantum theory together with the Poisson equation are solved numerically in this paper. The value of the fine-structure constant, are found, which are in good agreement with the experiment. The evaluation of the electrical form factor of such a particle is also carried out.
