Abstract

We have for the first time identified e+e--pairs produced by stronglyvarying electromagnetic fields in distant S-Pt collisions at 200 GeV/u projectile energy at the CERN-SPS. The differential cross section for the mass range 10 MeV/c2 less-than-or-equal-to m(ee) less-than-or-equal-to 100 MeV/c2 and the polar angle range 141 mrad less-than-or-equal-to theta(e) less-than-or-equal-to 260 mrad agrees well with a lowest-order perturbation QED-calculation.
