Following the Bargmann-Wigner formalism, wave-functions for integer and spin-3/2 fields are constructed within geometric algebra. This is achieved through the multiparticle space-time algebra, where the number of copies of the space-time algebra corresponds to the number of spinor fields needed to construct the wave-function. However, this formalism breaks down if a gauge field is introduced. This is resolved by introducing a, symmetrised version of the covariant derivative, such that it obeys the Duffin-Kemmer algebra. Furthermore, new interesting results are found for the energy-momentum tensors.
