Abstract

We incorporate the exchange interaction into a simulation in which all electron motion, including that involved in screening, is treated explicitly with a molecular-dynamics simulation run concurrently within an ensemble Monte Carlo treatment of scattering. Exchange is treated for the first time in such an approach by a semiclassical modification of the molecular dynamics that takes full account of the Fermi statistics, and, in particular, does not violate the exclusion principle. A comparison is made with the short-time relaxation data of Becker et al.
