Abstract: 
Dileptons can be produced through the mechanism of virtual bremsstrahlung during the deceleration of nuclei in relativistic heavy-ion collisions. The dilepton spectrum is studied in the framework of second order perturbation theory. Coherence effects are found to enhance the contributions to pair emission through constructive interference, since the main deceleration of nuclear matter in these collisions takes place in a small space-time region. Differential and total probabilities for lepton pairs are calculated for central U-238 + U-238 collisions at energies of 15 GeV/N and 60 GeV/N. Whereas the antisymmetrization of the lepton states plays a non-negligible role for the differential probabilities, it is not significant for the total probability.
