Direct three body dynamics govern ion atom recombination and barrierless termolecular reactions

Rian Koots, Marjan Mirahmadi, Jesús Pérez-Ríos

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-Ríos

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…

Chemistry in a Cryogenic Buffer Gas Cell

Qi Sun, Jinyu Dai, Rian Koots +4

Cryogenic buffer gas sources are ubiquitous for producing cold, collimated molecular beams for quantum science, chemistry, and precision measurements. The molecules are typically p…

Machine learning models for atom-diatom reactions across isotopologues

Daniel Julian, Rian Koots, Jesùs Pérez-Ríos

This work shows that feed-forward neural networks can predict the final ro-vibrational state distributions of inelastic and reactive processes of the reaction of Ca H2 $\righta…

PyQCAMS: Python Quasi-Classical Atom-Molecule Scattering

Rian Koots, Jesús Pérez-Ríos

We present Python Quasi-classical atom-molecule scattering (PyQCAMS), a new Python package for atom-molecule scattering within the quasi-classical trajectory approach. The input co…
