Abstract
By using an antisymmetrized molecular dynamics model (AMD), the data of kinematically complete events are compared with the experimental INDRA data through nuclear stopping in collisions at 10 to MeV. The sensitivity of the nuclear stopping is studied through interactions with different equations of state (EOSs) (soft and stiff) and in-medium cross sections in different energy domains. Above MeV, both EOSs and different cross sections can affect the nuclear stopping, but none of these parameters used in the AMD model can reproduce the experimental data at 20 to MeV. On the other hand, below MeV, nuclear stopping is not sensitive to both of the EOSs and the cross sections because of complete nuclear stopping. This indicates that some important mechanisms may be missing in AMD or that the selection of central collision events may be significantly different between the experiments and the simulations at this energy range.
