Nature of problem:
DCS computes differential cross sections for the electron-impact electronic excitation of diatomic molecules from the corresponding fixed nuclei T matrices.
The momentum transfer formalism is used to derive a convenient expression of the differential cross section.
The running time depends mostly on the number of channels included. The total time for the test run is 3.39s of which only 0.64s for the execution step.
