Abstract
We have computed finite temperature corrections to the electron-hadron scattering cross sections. These are based upon the renormalized elec tron mass and the modified density of states due to the presence of a background thermal bath. It is found that the electron-hadron thermal transport scattering cross section can be much larger than the zero te mperature one. In the case of electron-neutron transport scattering, w e find sigma(ne)(T)/sigma(ne)(T = 0) similar or equal to 5 at T simila r or equal to 0.1 MeV. [S0556-2821(98)06514-X].
