    "abstract": "Several observables of unbound nucleons which are to some extent sensitive to\nthe medium modifications of nucleon-nucleon elastic cross sections in\nneutron-rich intermediate energy heavy ion collisions are investigated. The\nsplitting effect of neutron and proton effective masses on cross sections is\ndiscussed. It is found that the transverse flow as a function of rapidity, the\n$Q_{zz}$ as a function of momentum, and the ratio of halfwidths of the\ntransverse to that of longitudinal rapidity distribution $R_{t/l}$ are very\nsensitive to the medium modifications of the cross sections. The transverse\nmomentum distribution of correlation functions of two-nucleons does not yield\ninformation on the in-medium cross section.",
