- Description:
- Measured and calculated differential cross sections(DCS) are contrasted through the generalized ocsillator strength for impact energies of 16, 20, 40, 54.4, 60, 75, 100 and 200 eV. The recently constructed universal formula by msezane and Sakmar is used to compare these results. Most of the results require renormalization and also show inaccuracy at small scattering angles. By also using the cubic spline function and the constructed formula from the universal formula, for the integral cross section by Chen and msezane, total cross sections are calculated. These integral cross sections which serve as a good check to the measured and calculated DCS indicated the importance and need for the integral cross section formula for small scattering angles as contribution from this region ranges from to of the total contribution. The need for the universal extrapolation formula is thus found to be crucially important for accurate extrapolation.
