The factorization of the scattering matrix for system of the Dirac equations on the whole axis

The factorization of scattering matrix for the non-self-conjugated system of the Dirac equation on the entire axis has been made. It has been established that if the scattering matrix of the Dirac equation system permits the factorization, /t he only potential will correspond to the latter. The factorization has served as a basis to obtain an unambiguity theorem for the inverse problem
