Direct three body dynamics govern ion atom recombination and barrierless termolecular reactions
Rian Koots, Marjan Mirahmadi, Jesús Pérez-RÃos
For over a century, termolecular, or third order, chemical reactions have been explained by the Lindemann Hinshelwood mechanism, assuming sequential stabilization via bimolecular e…

Direct three-body atom recombination: halogen atoms
Rian Koots, Grace Ding, Jesús Pérez-RÃos
The recombination of halogen atoms has been a research topic in chemical physics for over a century. All theoretical descriptions of atom recombination depend on a two-step assumpt…
