Resonance during a reactive scattering process has been an interest for decades but our ability to study and understand this phenomenon continues to grow with advancements in computational power and experimental ability. These signals are the result of coupling between a scattering state of the system and a trapped state of the reaction potential. Three known types of resonance are shape, barrier, and Feshbach resonance. For each of these different resonance types, the scattering state couples with a differ type of potential state. The goal of this worksheet is to use simple and familiar models in order to introduce the concept of resonance in reactive scattering and to explore the three different types of resonance. This worksheet uses the Maple Quantum Chemistry Toolbox.
