Nature of problem:
The code calculates total and differential cross sections for the single ionization of target atoms ranging from hydrogen up to and including argon by both light and heavy ion impact.
ARGON allows the user to calculate the cross-sections using either the CDW or CDW-EIS models within the wave treatment.
Both the CDW and CDW-EIS models are two-state perturbative approximations.
Times vary according to the input data and number of processors. For one processor the test input data for double differential cross sections (40 points) took less than one second, whereas the test input for total cross sections (20 points) took 32 minutes.
