Absolute low-energye−-Ar scattering cross sections

Relative measurements of $e^{\mathrm{-}}$-Ar angular distributions in the energy range 3–20 eV have been placed on an absolute scale by both a phase-shift analysis and relative flow normalization. The two sets of absolute differential cross sections are in excellent agreement with each other over the entire energy range. These measurements are also in agreement with previous calculations and measurements in different energy and angular ranges. Total cross sections calculated from the derived phase shifts are in excellent agreement with recent direct experimental determinations.
