    Notes: Abstract The emission of nucleons in central collisions of mass symmetric and asymmetric systems in the intermediate energy regime is investigated within a quantal phase-space approach including mean field as well as two-body collision dynamics. The very energetic tails of the particle spectra are found to originate from high momentum components of the nuclear wave function as well as from successive two-body scattering. Furthermore, the angular distribution of energetic light particles for mass symmetric systems turns out to depend on the effective nucleon-nucleon cross section in the nuclear medium and might be used to determine this quantity experimentally.

    Notes: Abstract We derive a transport equation for the description of non-relativistic heavy-ion collisions from time-dependentG-matrix theory. The approximations introduced are investigated within a modified Lipkin model on theA-body level and by one-dimensional calculations for colliding finite fermion systems on the two-body level. Both approximations are found to hold reasonably well. The classical limit of these equations in phase space yields a transport equation of the Vlasov-Uehling-Uhlenbeck type without double counting of interactions and uniquely determines the time-dependent mean field as well as an in-medium nucleon-nucleon cross-section on the basis of the sameG-matrix.

    Notes: Abstract The production of pions in intermediate energy nucleus-nucleus collisions by incoherent nucleon-nucleon collisions is studied within a microscopic quantal phase-space approach. Employing free production rates for the elementary processN+N → π+X experimental data for inclusive pion yields are approximately reproduced from 20–150 MeV/u within the first collision approximation. These results indicate that cooperative phenomena — apart from the time-dependent mean field — seem to play a minor role for energetic particle production even at very low bombarding energy.
