الوصف: The scalar particle production from vacuum in the presence of electric field, on the de Sitter spacetime is studied. We use perturbation methods to define the transition amplitude. We obtain that the momentum is not conserved in this process. The probability of pair production is computed by squaring the transition amplitude. Our graphical representations shows that, the probability of scalar particle production was important only in early stage of the universe, when the Hubble's constant was very large in comparison with the mass of the particle. Also we propose here a criteria of particle-antiparticle separation.
