First we will review equation of motion of Dirac and Maxwell, and then construct the equation for spin 3/2 in the similar fashion. Our method actually a generalization of relativistic equation of motion based on spin operator and Hamiltonian similar to Dirac and Maxwell equation in ref. [1] pp. 50. Furthermore, we could not bring the equation to the Klein Gordon limit for every wave function component in spin 3/2 formalism.General Physicstext
