Abstract
We calculate the elastic nucleon-nucleon cross section in symmetric nu clear matter at finite temperature by determining the nonrelativistic in-medium scattering matrix with a realistic nucleon-nucleon potential . We define average in-medium cross sections depending on density and temperature and provide simple parametrizations for the use in numeric al simulations of heavy-ion collisions. The effect of hole-hole propag ation in the nuclear medium is found to be small.
