“…For the N 2 and O 2 molecules under study, several results in the literature are in very good agreement with experimental data using the IAM method down to energies of 50 eV [139,140]. For this reason, and because of its simplicity, we consider it the best option for our application.…”

The study of ions in the gas phase has a long history and has involved both chemists and physicists. The interplay of their competences with the use of very sophisticated commercial and/or homemade instrumentations and theoretical models has improved the knowledge of thermodynamics and kinetics of many chemical reactions, even if still many stages of these processes need to be fully understood. The new technologies and the novel free-electron laser facilities based on plasma acceleration open new opportunities to investigate the chemical reactions in some unrevealed fundamental aspects. The synchrotron light source can be put beside the FELs, and by mass spectrometric techniques and spectroscopies coupled with versatile ion sources it is possible to really change the state of the art of the ion chemistry in different areas such as atmospheric and astro chemistry, plasma chemistry, biophysics, and interstellar medium (ISM). In this manuscript we review the works performed by a joint combination of the experimental studies of ion–molecule reactions with synchrotron radiation and theoretical models adapted and developed to the experimental evidence. The review concludes with the perspectives of ion–molecule reactions by using FEL instrumentations as well as pump probe measurements and the initial attempt in the development of more realistic theoretical models for the prospective improvement of our predictive capability.

“…Alternatively, there have been some publications centered on a considerably simpler analytical [27,28] description of the DCS or a partial-wave [29][30][31] analysis applied to an analytical optical potential, which yielded reasonable results over different ranges of validity. So far, accuracy in producing outputs has been pushed jointly with the level of sophistication while using approximations to abridge computational costs where appropriate.…”

A simple model is proposed to compute electron-diatomic molecule elastic differential cross sections at intermediate energies within the framework of an analytical local optical potential. In a spherical harmonic expansion of the molecular potential we treat the isotropic term with the partial-wave decomposition and apply the independent atom model (IAM) on all higher orders. This model is seen to properly converge to the IAM at high energies, while bringing significant improvement at lower energies. We compare the results with a well-tested program called ELSEPA, tailored for high-energy electron-atom scattering and address its further extension to molecules with the method proposed. The simplicity of the calculations and the encouraging agreement in shape with experimental data could promote attractiveness among plasma physics simulations in need of coherent and well-resolved differential cross sections.

“…In addition, Lee and Iga [4] computed integral and momentum transfer cross-sections for scattered waves by combining the Schwinger variational iterative method and the distorted-wave approximation approach at higher energies (20-800 eV). On the other side, elastic scattering of electron from this molecule is highly worked both by experimentalists and theoreticians [1,[5][6][7][8][9][10][11].…”

In the field of molecular collisions, there has been a kind of rebirth with respect to the scattering of electrons both experimentally and theoretically. From experimental point of view, most data are available only in a limited energy and angular range. From the theoretical side, new and different models have been developed and experimental data is needed to test these theoretical models. The basic concept in elastic scattering of electrons from atoms and molecules is the differential cross-section (DCS). As a function of scattering angle and electron impact energy the cross-sections can be measured and these results reveal important information about projectile, target and also about the atomic and molecular structures. In this work experimentally measured DCSs for elastic scattering of electrons by molecular nitrogen are presented.
