Intrinsic Magnetic Moment of Elementary Particles of Spin $\frac{3}{2}$

Fierz-Pauli's theory of spin-$\frac{3}{2}$ particles has been reformulated in a manner somewhat resembling the usual formulation of Dirac's equation for the electron. The discussion is simplified by complete reduction of the representation of the spatial rotation and reflection group by the field. The dependent variables can then be expressed in terms of the spin-$\frac{3}{2}$ field. The magnetic moment and the gyromagnetic ratio of "bare" spin-$\frac{3}{2}$ particles of charge $q$ and mass $m$ are found to be ($\frac{q\hslash }{2mc}$) and ($\frac{q}{3mc}$), respectively.
