Abstract: The lowest order contribution of the amplitude of Dirac-Coulomb scattering inde Sitter spacetime is calculated assuming that the initial and final states ofthe Dirac field are described by exact solutions of the free Dirac equation onde Sitter spacetime with a given energy and helicity. We find that the totalenergy is conserved in the scattering process.
