Description

Electron and positron emission spectra produced in heavy-ion collisions with beam energies in the range Elab=8--100 MeV/nucleon are calculated up to kinetic lepton energies of 50 MeV. Earlier predictions concerning the observability of nuclear stopping times in the range τ=1--10 fm/c by means of the slope of δ-electron spectra are confirmed. However, the effect of time delay is somewhat less pronounced than predicted in first-order perturbation theory
