| 英文摘要 | Based on the isospin-dependent Boltzmann-Uehling-Uhlenbeck (IBUU04) transport model, we explored effects of in-medium NN elastic scattering cross section and nuclear symmetry energy on the subthreshold pion production in the Sn-132 + Sn-124 reaction. We find that, with the decrease of the incident beam energy, the effects of the in-medium NN elastic scattering cross section on the pi(-)/pi(+) ratio are larger than that of the symmetry energy, although the latter may be also larger. While keeping the effect of symmetry energy, the double ratio of pi(-)/pi(+) from neutron-rich and neutron-poor reaction systems (with the same mass number of system) Sn-132 + Sn-124 and Pm-128 + Pm-128 almost fully cancels out the effects of the in-medium NN elastic scattering cross section. |
