Abstract
The total cross sections (TCS) for 0.7-400 eV positrons and 1.0-400 eV electrons scattered by benzene (C6H6) vapour molecules obtained by a relative method are presented. The values of TCS for positrons at low energies are very high, and the positron scattering at low energies is found to be sharply forward peaked. On the other hand, the TCS values for electrons decrease with decreasing energy at low energies. The positronium (Ps) formation cross sections are rather low in comparison with the TCS.
