Abstract
In the standard development of scattering theory the Hamiltonian of the system plays a central role: however when the Bakamjian-Thomas method is used to construct a relativistic model of a few-particle system, the mass operator plays the essential role. Here a simple procedure for translating the Hamiltonian formulation of scattering theory to a mass-operator formulation is given. A simple proof of the Poincaré invariance of the S operator that is obtained from a Bakamjian-Thomas model is also given.
