Electron Impact Collision Estimations for Different Cross Sections On Atomic and Molecular Targets & Its Biological Relevance

PHYSICS

In this article we have reported ionizing cross-sections of total electron impacts from the ionization threshold to 2000 eV for the bio-molecules, pyridine, n-propylamine, urea, formamide and N-methylformamide. The current calculations are based on the complex spherical optical formalism and complex ionization potential contribution method. For pyridine and pyrimidine, the results obtained are compared to available theoretical and experimental results and are in good agreement with existing data. For other molecules, the cross sections of ionization are first reported. There is also an interesting relationship between the inelastic peak and ionization sections with target parameters. It was found that the two cross-sections depend on those parameters as much as possible, which confirms the consistency of the values shown here.
