Abstract:
This work presents a detailed study concerning the quantum isotope effects on the H+Li[Formula: see text] reaction, when the hydrogen is replaced by muonium, deuterium, and tritium. To verify such effects on these isotope reactions, it was applied an accurate time-independent quantum scattering approach to determine the dynamic properties, such as state-to-state probabilities as a function of the total energy, the product energetic distribution, and the contribution of the ro-vibrational excitation on the reaction probabilities. From the obtained results, it was possible to observe a significant increase on the promotion of the H+Li2 reaction when hydrogen is replaced by tritium. This fact shows the importance of the isotopic substitution in the making and breaking of the chemical bonds in the reactive systems.
