ELECTRON-HADRON SCATTERING IN STRONG MAGNETIC-FIELDS

We study the effect of the external magnetic field on the scattering o f an electron off a free hadron in the ultrarelativistic limit of elec trons. In this work, the electrons are specifically assumed to he init ially in their lowest Landau level. Our calculations show that the cro ss sections seriously depend on the external magnetic field for the fi xed initial electron energy, As the magnetic field strength increases, above some critical value B-c, the cross section of electron-neutron scattering increases continuously, while that of electron-proton scatt ering becomes constant. Both of them decrease drastically as the magne tic field strength decreases below B-c.
