We give also a method for its computation. The calculations are carried out explicitly for electromagnetic, gravitational, and short-range scalar interactions up to the linear terms in the slow-motion approximation. The contribution of the spin-spin terms is found to be at best 10-6 times the post-Newtonian ones for the gravitational interaction.8 p.application/pdfeng(c) The American Physical Society, 1983ElectromagnetismeGravitacióInteraccions febles (Física nuclear)Partícules (Física nuclear)ElectromagnetismGravitationWeak interactions (Nuclear physics)Particles (Nuclear physics)info:eu-repo/semantics/article79587info:eu-repo/semantics/openAccess
