The authors report on theoretical calculations of differential and partial cross sections for elastic scattering of electrons from Ar{sup +} and total cross sections for electron-impact excitation and ionization of Ar{sup +}. The elastic scattering calculations are performed using the R-matrix method and are compared to measurements. The excitation cross sections are calculated using both the distorted wave and the R-matrix close-coupling approximations, while the ionization cross sections are determined from the distorted-wave approximation, and include the effects of final-state correlation. The effects of core polarization and resonance contributions on the excitation cross sections are examined carefully. Rate coefficients for ionization and excitation to the levels of 3p{sup 4}4p {sup 4}D, together with radiative rates from the levels of 3p{sup 4}4p {sup 4}D to all possible lower levels, will be entered into the ADAS collisional-radiative modeling codes to generate density-dependent parameters for use in the interpretation of on-going emissivity measurements from tokamak plasmas.
