We present the results of a complex ab initio optical potential calculation of elastic electron and positron scattering from argon atoms. The inclusion of the absorption part of this potential markedly improves the agreement of our results with experimental measurements. Most notably, the differential cross section for electron scattering is reduced in the mid-angular range while for positron scattering the shape of the differential cross section is substantially altered to conform to that...[Show more]
