ION calculates total and singly and doubly differential cross sections for the ionization of hydrogen-like atoms by fully stripped ions. The cross sections may be calculated using any one of the four theoretical descriptions shown below:

1. The First Born Approximation

2. The Distorted Wave Born Approximation

3. The Continuum Distorted Wave Approximation

4. The Continuum Distorted Wave Eikonal Initial State Approximation
