Abstract.
Based on the isospin-dependent transport model IBUU and on the scaling model according to nucleon effective mass, effects of elastic and inelastic NN scattering cross-sections on \( \pi^{{-}}_{}\)/\( \pi^{{+}}_{}\) in the neutron-rich reaction 48Ca + 48Ca at a beam energy of 400MeV/nucleon are studied. It is found that cross-section effects of both NN elastic and inelastic scatterings affect \( \Delta_{{1232}}^{}\) , \( \pi^{{-}}_{}\) and \( \pi^{{+}}_{}\) productions as well as the value of \( \pi^{{-}}_{}\)/\( \pi^{{+}}_{}\) .
