Low energy electron interaction and dissociative ionization of pyridazine

Abstract

Pyridazine, an important biomolecule used as a radiosensitizer in cancer treatment, is investigated in this work. The collision processes like elastic scattering and dissociative ionization of pyridazine are specifically studied here. The Single-Center Expansion method (SCE) is applied to obtain the cross-sections like differential, integrated, and momentum transfer cross-sections in the energy range of 1 eV to 100 eV. Additionally, the modified Binary Encounter Bethe method (mBEB) and mass spectrum dependence method (MSD) are applied to compute the partial ionization cross-sections to understand the dissociative ionization process. The obtained cross-sections are consistent and have good agreement with available theoretical and experimental data. Most of the results of elastic cross-sections and partial ionization cross-sections are calculated for the first time, providing valuable insights into the interaction of electrons with the pyridazine molecule. The present data could be used in Monte Carlo structural codes to understand the radiation induced DNA/RNA damage in the living cells.
