Abstract
The integrals of motion of the Dirac-equation generalized byRayski are discussed. The introduction of the operator of the total momentum is suggested and its properties are investigated. It is pointed out that the presence of the internal field induces beside the local momentum of the field an internal momentum completing it to the total one, the justification for its introduction being also supported by the investigation of the infinitesimal operator of rotation. In the suggested method commutation rules corresponding to the usual ones are fulfilled. Finally, the generalization of the field equation is briefly discussed.
