Figures from reference [26]. The new GS revised model including the Mott correction is indicated as “Opt4” on the two top angular plots (blue triangle). The GS model without this correction is indicated as “GS” (pink open cross marker). The bottom plots show the e⁻ backscattering coefficient as function of energy on aluminum and gold targets. The yellow curve is obtained with the default “Urban” model, the blue one is for the new GS revised implementation.
