The Klein-Gordon equation is formed by two potentials coupling which are the four-vector potential (V(r)) and scalar potential (S(r)).
where [A.sub.[mu]] is the four-vector potential, [V.sub.s] is the scalar potential, and [[PSI].sub.K](t, [??]) is the sixteen components wavefunction of the DKP equation.
Interchanging the order of partial differentiation in the term [[A.sup.[micro];v].sub.[micro]] and using the Lorentz condition of (16), we obtain the well-known wave equation for the four-vector potential [14, see pp.
