Total and differential cross sections for positron and electron impact on argon atoms are compared in order to show their similarities and differences. These comparisons provide information as to how antimatter-matter atomic interactions are like, or different from, matter-matter interactions that are normally encountered. Plus such comparisons provide information about how simply changing the direction of the coulomb field in atomic interactions influences the interaction probabilities and the kinematics. Data taken from the literature are used for these comparisons. The selected data are considered to be the most reliable available and representative of the many studies performed to date.

Keywords: Antimatter, Atomic collisions. Positron impact, Charge effects, Coulomb interaction, Differential cross sections, Elastic collisions, Electron impact, Electron correlation, Ionization, Inelastic collisions, Shake-off, TS-1.
