dc.descriptionIn a recent work, we have proposed an empirical scaling factor to the quasi-free scattering model absorption potential of Staszewska et al., in order to account for many-body interactions in the electron-molecule scattering problem. In this work we extend the application of this modified potential to the study of electron collisions with three molecular targets of different geometric arrangements: linear (CO), angular (H2O), and tetrahedral (CH4), in a wide energy range. The calculations were performed using the same scaling factor without any additional adjustment. We have observed a significant improvement in the agreement between the calculated results and the experimental data available in the literature, in comparison with that of the calculated results without the scaling factor. Also, this study reinforces the fact that the proposed correction factor is independent of targets and therefore can be used for predictive purposes for a general target. (c) 2007 Elsevier B.V.
