A theoretical investigation on differential, integral, momentum transfer, viscosity cross sections and spin polarization for elastically scattered electrons positrons from Ar atoms in the energy range 1 eV ≤ Ei 0.5 GeV is presented. In addition, we have studied critical minima elastic differential sections, absorption, total ionization sections. Two different approaches, depending upon incident energy, are employed solving relativistic Dirac equation with partial-wave decomposition. The solution of involves use either complex optical-model potentials or only nuclear at higher energies. comparison present results available experimental data other findings produces a reasonable agreement throughout investigated range.
