Dirac partial wave calculation for electron scattering cross section by nucleic acid bases

Abstract

Abstract Differential, total, elastic and inelastic scattering cross sections due to the electron impact on the primary nucleic acid bases, are calculated with relativistic Dirac partial-wave considering a local interaction potential known as spherical complex optical potential model. The electron scattering is modeled by implementing screening-corrected additivity rule, a modified form of independent atom model, over an energy range of 10–20000 eV. Comparisons of results obtained in this work with other theoretical and experimental approaches are also presented.
