Coupled-channel results for atomic excitations in intermediate-energy heavy-ion collisions
Physical Review C1989Vol. 40(2), pp. 752–761
Abstract
Electron and positron emission spectra produced in heavy-ion collisions with beam energies in the range ${E}_{\mathrm{lab}=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 \ensuremath{\tau}=1--10 fm/c by means of the slope of \ensuremath{\delta}-electron spectra are confirmed. However, the effect of time delay is somewhat less pronounced than predicted in first-order perturbation theory.
