Programming language: Fortran.
Computer: VAX-9000.
Operating system: VMS VERSION 5.4-2.
RAM: 704K words
Word size: 32
Keywords: Molecular physics, Scattering, Elastic, Single ionisation, Fully stripped Projectile ion, Hydrogenic target, First born, Distorted wave born, Continuum distorted wave, Eikonal initial state.
Classification: 16.7.

Nature of problem:
ION calculates total and differential cross sections for the ionization of hydrogen-like atoms by the impact of multi-charged fully-stripped ions.

Solution method:
ION allows the user to calculate cross sections using any one of four theoretical models, namely the first Born (B1), Distorted Wave Born (DWB), Continuum Distorted Wave (CDW), or Continuum Distorted Wave Eikonal Initial State (CDWEIS) approximations.

Restrictions:
The four theoretical models are all two state approximations.

Running time:
About 1 minute per energy for total cross sections on a VAX-9000.
