Abstract:	We show the mathematical formulation of the process of pair production in electromagnetic fields for spinless particles. We compute the probability that ? pairs are created in the semiclassical approximation, and we prove that, in this approach, the pair creation phenomenon is a stochastic Poisson process. Finally, we give a rigorous demonstration and a suitable interpretation of the Schwinger formula.
