A number of particle properties stem from the use of as adjunctator (Bargmann-Pauli) in the Dirac theory (spin alignment, Dirac current, etc.). The early motivations for accepting as adjunctator were representation-dependent, mildly bearing relation to the actual conditions forcing as adjunctator. Representation-independent approaches to the physical predictions of the Dirac equation are somewhat new, here presented as being the reasons for as adjunctator of the Dirac theory, together with the essential role of the latter in the physical aspects of the theory.
