Numerical Calculations of the Rotational Excitation of a Diatomic Molecule Upon Collision with a Structureless Atom

Exact Numerical values for the transition probabilities between rotational states of a rigid diatomic molecule colliding with a structureless atom were obtained using “The Amplitude Density Function” Technique. Particular attention was given to the influence of a closed channel on the transition probabilities between open channels. Resonances corresponding to bound states in the closed channel were demonstrated, and the results were shown to agree with general resonance theory.
