We determine its feasibility with current technology and its limitations. As an example we work out the parameters to model the reaction F+H2 → H+HF by the propagation of ultracold lithium atoms.5eng© 2011 IOP Publishing Ltd.Ultracold atomsChemical reactionsSimulation of quantum collinear chemical reactions with ultracold atomsQuantum simulation of a triatomic chemical reaction with ultracold atoms on a waveguideresearch articleFísicaQuímicahttps://doi.org/10.1088/0953-4075/44/19/195302open access119, 1953025JOURNAL OF PHYSICS B-ATOMIC MOLECULAR AND OPTICAL PHYSICS44AR/0000026571
