Abstract

Using the small acceleration approximation we derive a relativistic scalar-vector force from a modified Zimányi-Moszkowski Lagrangian based on σ, ω and ρ meson exchanges. The momen-tum dependence of the force is fixed automatically by the theory. We present an application of such a force in a QMD calculation at intermediate energies comparing the results with the experimental ones published recently by the FOPI collaboration. For most of the quantities (number of intermediate mass fragments, ERAT, integrated side flow, central flow, charge distributions, etc.) we find agreement with the experimental results.
