Abstract：
The medium effects on the nucleon-△ elastic and inelastic scattering cross sections are investigated within the framework of self-consistent relativistic Boltzmann-Uehling-Uhlenbeck approach. The results show that at SIS energy range the in-medium cross sections deviate substatially from the Cugnon's parametrization.So, the medium effects must be taken into account.
