    "abstract": "A quasipotential formalism for elastic scattering from relativistic bound\nstates is based on applying an instant constraint to both initial and final\nstates in the Breit frame. This formalism is advantageous for the analysis of\nelectromagnetic interactions because current conservation and four momentum\nconservation are realized within a three-dimensional formalism. Wave functions\nare required in a frame where the total momentum is nonzero, which means that\nthe usual partial wave analysis is inapplicable. In this work, the\nthree-dimensional equation is solved numerically, taking into account the\nrelevant symmetries. A dynamical boost of the interaction also is needed for\nthe instant formalism, which in general requires that the boosted interaction\nbe defined as the solution of a four-dimensional equation. For the case of a\nscalar separable interaction, this equation is solved and the Lorentz\ninvariance of the three-dimensional formulation using the boosted interaction\nis verified. For more realistic interactions, a simple approximation is used to\ncharacterize the boost of the interaction.",
