Programming language used: Fortran 90/MPI
Computer:
DEC Alpha 21164 ,
IBM SP2 ,
SUN Enterprise 3500 .
Nature of physical 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.
Method of solution:
ARGON allows the user to calculate the cross-sections using either the
CDW or CDW-EIS models within the wave treatment.
Restrictions:
Both the CDW and CDW-EIS models are two-state perturbative
approximations.
Typical running time:
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.
