Abstract
We demonstrate that the predictions of the n-body quantum molecular dynamics (QMD) approach to heavy-io n collisions does indeed agree with those of the well-established one-body VUU/BUU theory, as far as single-particle observables are concerned. We find in particular good agreement of the longitudinal and transverse momentum transfer, the particle multiplicities and the double differential cross section in the two approaches. These predictions could be checked experimentally via exclusive 4π measurements. Omitting collisions, QMD results agree with that of TDHF and of the Vlasov equation. Thus neither the details of the TDHF wave function (which are not reproduced in Vlasov and QMD) nor the parametrization of the single-particle Wigner densities as gaussians with a constant width (which is employed in QMD) do play a decisive role for intermediate-energy heavy-ion collisions.
