Elastic electron scattering from the DNA bases: cytosine and thymine

Relative elastic differential cross sections for elastic scattering from cytosine and thymine have been measured using the crossed-beam method. The measurements have been performed at two electron energies of 500 and 100 eV, and cover the angular range of 10°-130°. Calculations of elastic differential cross sections have been performed via the screen corrected additivity rule method, and agreement is quite good with the present experimental results. The results obtained are important for the modelling of energy deposition in living tissue.
