FM 73.7: Talk

Thursday, September 26, 2019, 15:30–15:45, Aula

State-to-state chemistry with resolution of magnetic spins — •Markus Deiss, Joschka Wolf, Shinsuke Haze, and Johannes Hecker Denschlag — Institut für Quantenmaterie and Center for Integrated Quantum Science and Technology IQ^ST, Universität Ulm, 89069 Ulm, Germany

State-to-state chemistry describes the determination of the quantum states of the final products given the quantum state of the reactants. We have developed and demonstrated a method to probe molecular product states of reactive processes both qualitatively and quantitatively [1]. Using the given method, we have investigated the recombination of three neutral rubidium atoms in an ultracold atomic gas. Now, we have extended the scheme of [1] to also resolve the magnetic quantum number of molecular product states. In this talk, measurements of product molecules as a function of the magnetic field strength and for different reactant states are presented. We can formulate a propensity rule with respect to the magnetic quantum number.
