Total electron scattering cross sections of molecules containing H, B, C, N, O, F, Si, P, S, and Cl in the energy range 0.1- 6.0 keV.
The effective atomic total electron scattering cross sections (EATCS) of atomic H, B, C, N, O, F, Si, P, S, and Cl are proposed for 0.1-6.0 keV energies using the existing experimental total electron scattering cross sections (TCS) of simple molecules consisting of these atoms. Based on the EATCS , a simple empirical model depending on the symmetry and geometry of molecule is developed to predict the TCS of H, B, C, N, O, F, Si, P, S, and Cl containing molecules in the energy range 0.1-6.0 keV. The TCS of important biomolecules 2-Butanone Formamide, Trimethylamine, Aniline, Pyrimidine, Anthracene, five nucleic bases (adenine, cytosine, guanine, thymine and uracil) , Phosphoric acid, sugar substitute (Tetrahydrofuran, Furan, Tetrahydropyran, 3-hydroxytetrahydrofuran, D-Glucose, and alpha-D-glucose), and simple amino acids (Glycine, Lysine and L-histidine) in the energy range 0.1-6.0 keV are predicted using the model. The reliability of these predictions are verified by comparing the determined TCS with the available experimental and theoretical cross sections.
