Probability current in the relativistic quantum mechanics

Abstract:
The probablity current for a quantum spinless relativistic particle is introduced in the context of the Hamiltonian approach utilizing the Foldy-Salpeter equation as an alternative of the Klein-Gordon equation. The presented formalism is illustrated by examples of exact solutions to the Foldy-Salpeter equation.
