    "abstract": "The importance of a isospin dependent nuclear mean field (IDMF) in regard to\nthe pion production mechanism is studied for the reaction $Au+Au$ at 1\nGeV/nucleon using the Quantum Molecular Dynamics (QMD) model. In particular,\nthe effect of the IDMF on pion spectra and the charged pion ratio are analyzed.\nIt is found that the inclusion of a IDMF considerably suppresses the low$-p_t$\npions, thus, leading to a better agreement with the data on pion spectra.\nMoreover, the rapidity distribution of the charged pion ratio appears to be\nsensitive to the isospin dependence of the nuclear mean field.",
