Abstract
A theoretical analysis of collective momentum transfer is performed in heavy-ion reactions below 100 MeV/nucleon in the Landau-Vlasov approach. The nucleon-nucleon cross section, atomic mass, compressibility, and effective mass dependences are analyzed. The simulation of detector acceptances and of finite number of detected particles are discussed. In connection with recent experiments, theoretical results and experimental data are confronted taking into account the experimental constraints. Finite range forces of the Gogny type connected with different nuclear matter incompressibilities are used and the ensuing sensitivity of the flow is studied. The question whether the flow provides information on out-of-equilibrium matter properties is investigated.
