The production of prompt positrons in pp-collisions at ..sqrt..s = 63 GeV and y - 0 has been measured as a function of the associated charged particle multiplicity over the P/sub T/ internal 0.12 < P/sub T/ < 1.0 GeV/c. Preliminary results indicate that the production of positrons is proportional to the square of the mean multiplicity at low P/sub T/ (< 0.4 GeV/c). Such a square dependence is not expected from final state sources such as hadronic bremsstrahlung or hadronic decays. It could however indicate a production mechanism of the soft lepton continuum over an extensive volume during the early stages of the collision.
