It is a well known fact that the Dirac and Kemmer - Duffin equations are the Bhabha equations. We use the method based on the de Sitter group SO(1,4) to show that the Rarita - Schwinger and Bargmann - Wigner equations can also be treated as the Bhabha equations with some subsidiary conditions. This demonstrates that the de Sitter group can be considered as a significant auxiliary group which provides a unified approach to the equations of relativistic quantum theory.
