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…
Electronic properties of the Radium-monochalcogenides RaX (X = O,S,Se) and RaO+/- ions
Mateo Londoño, Jesús Pérez-RÃos
We present a theoretical investigation on the electronic structure and properties of radium monochalcogenides, with chalcogens O, S, and Se, as well as the ionic species RaO +/-. O…
Pushing the Limits of Atomic Dark Matter: First-Principles Recombination Rates and Cosmological Constraints
Jared Barron, Rouven Essig, Megan H. McDuffie +2
Minimal atomic dark matter with its distinctive cooling mechanisms offers an instructive framework for understanding the potential impact of dark matter on small-scale structure fo…
Coordination-driven magic numbers in protonated argon clusters
Saajid Chowdhury, MarÃa Judit Montes de Oca-Estévez, Florian Foitzik +6
The structural properties of rare-gas clusters can be primarily described by a simple sphere packing model or by pairwise interactions. Remarkably, adding a single proton yields a…
