Triple differential cross sections (TDCS) of the argon 3s and 3p outer shells were obtained from electron-impact ionization (e,2e) experiments with coplanar equal-energy sharing scattering geometries. The advantages of a new asymmetric equal-energy-scattering geometry are described. Data are reported for incident electron energies of 2020, 1220, 620, and 420 eV. Measurements extend to the high-binding momentum region of the TDCS. The data are compared with recent distorted-wave calculations, with a view to determining the range of validity of the models for coplanar equal-energy-sharing kinematics.
