Abstract
The absorption potential of Staszewska et al. (Phys. Rev. A 28 (1983) 2740) is known to underestimate the experimental values of the elastic differential, integral and momentum transfer cross sections. Hence, it has been modified and applied to study the elastic scattering of electrons on molecular oxygen at intermediate energies. A comparison of the elastic cross section results, obtained by using modified absorption potential, with the experimental data shows a significant improvement over the unmodified absorption potential results. The differential, integral and momentum transfer cross sections obtained using the modified absorption potential are in very good agreement with the experimental data.
