“…The DCS ratios measurements and calculations were extended recently to another rare gas target, that is Xe [66], for which the agreement between experiments and the DBSR theory is found to be less than that for Kr. Therefore, further improvement of theoretical approaches is still necessary for electron scattering processes that involve multi-electron atomic targets as described in [66].…”

Much effort has been devoted to describing qualitatively and quantitatively electron scattering processes due to their ever-increasing importance in many industrial and medical applications. We present achievements made in the last years, focusing on some of the advancements and recent progress in the field. Particular reference is made on concrete case studies to probe the level of accord in cross-section data obtained from experiments and theory, as well as on selected instrumentation developments to probe dynamics of dissociative processes induced by electron impact. We stress that the purpose of this colloquium paper is not to be a comprehensive review but rather to provide a snapshot of different research topics in electron scattering by pointing out certain challenges and, therefore, indicating opportunities to facilitate further experimental and theoretical work.

We report on a series of detailed Breit-Pauli and Dirac B-spline R-matrix (DBSR) differential cross section (DCS) calculations for excitation of the $$5\,^2\mathrm{S}_{1/2} \rightarrow 5\,^2\mathrm{P}_{1/2}$$ 5 2 S 1 / 2 → 5 2 P 1 / 2 and $$5\,^2\mathrm{S}_{1/2}\rightarrow 5\,^2\mathrm{P}_{3/2}$$ 5 2 S 1 / 2 → 5 2 P 3 / 2 states in rubidium by 40 eV incident electrons. The early BP computations shown here were carried out with both 5 states and 12 states, while the DBSR models coupled 150 and 325 states, respectively. We also report corresponding results from a limited set of DCS measurements on the unresolved $$5\,^2\mathrm{P}_{1/2,3/2}$$ 5 2 P 1 / 2 , 3 / 2 states, with the experimental data being restricted to the scattered electron angular range 2–$$10^\circ $$ 10 ∘ . Typically, good agreement is found between our calculated and measured DCS for excitation of the unresolved $$5\,^2\mathrm{P}_{1/2,3/2}$$ 5 2 P 1 / 2 , 3 / 2 states, with best accord being found between the DBSR predictions and the measured data. The present theoretical and experimental results are also compared with predictions from earlier 40 eV calculations using the nonrelativistic Distorted-Wave Born Approximation and a Relativistic Distorted-Wave model.
