    "abstract": "The ratio of pre-equilibrium neutrons to protons from collisions of\nneutron-rich nuclei is studied as a function of their kinetic energies. This\nratio is found to be sensitive to the density dependence of the nuclear\nsymmetry energy, but is independent of the compressibility of symmetric nuclear\nmatter and the in-medium nucleon-nucleon cross sections. The experimental\nmeasurement of this ratio thus provides a novel means for determining the\nnuclear equation of state of asymmetric nuclear matter.",
