“…There have been a number of calculations [38,41,[51][52][53] and experiments [31,40,47,49,50,54,55]. The MCHF calculation was a completely ab initio calculation focused on describing low-energy elastic scattering [38,53].…”

A generalization of the box-variational method is developed to describe particle scattering with the Dirac equation. The method is applied to extract phase shifts from all-order single + double relativistic many-body perturbation theory calculations of the electron-helium, electron-neon, and electron-krypton systems. Comparisons with experimental elastic and momentum transfer cross sections are made. Agreement at the 1% to 2% level is achieved for helium and neon. The scattering length for krypton is 4% smaller in magnitude than experimental estimates derived from swarm experiments.

“…Furthermore, we do not know details of their experimental procedures and setup. On the other hand, experimental TCS of Ferch was determined using well-described time of flight (TOF) system purposely designed for very low-energy electron scattering [37].

Modified effective range theory formulated as a Bayesian statistical model through the combination with Markov Chain Monte Carlo integration and fitting techniques is used to check the compatibility of different e − −Xe scattering data such as the total cross-sections, the momentum transfer cross-sections, and the differential cross-sections that were determined experimentally in the region of Ramsauer-Townsend minimum. On the basis of this predictive approach, the most probable value of the scattering length, (−6.51 ± 0.05)a 0 , is proposed. The present analysis suggests that the non-relativistic spinless effective range theory is suitable for the description of angular and energy dependencies of e − −Xe elastic scattering cross-sections below the threshold for first inelastic process.
