Using a collisional-radiative model to validate e-Xe$^+$ cross sections calculated by the Dirac B-spline R-matrix approach*

Experimental studies of e-Xe$^+$ collisions are difficult to carry out. Consequently, a direct comparison between cross-section data obtained theoretically and experimentally is hard to achieve. In this work, a collisional-radiative (CR) model based on e-Xe+ cross sections calculated by the Dirac B-Spline R-Matrix method is used to validate the predicted cross sections. This is achieved by comparing level density distributions predicted by the CR model and those determined experimentally.
