Nature of problem:
Multistate molecular treatment of atomic collisions in the impact parameter approximation. Calculation of the transition amplitudes for straight-line case.

Solution method:
The coupled first-order differential equations are integrated by the method of Bulirsch and Stoer. The integrals over energy differences are integrated by Simpson's rule.

Restrictions:
Linear trajectories only.

Running time:
Running times for the test run: on the IRIS 80: 0.65 min, on the IBM 360-65: 48 s, on the IBM 370-165: 34 s.
