Phys. Rev. A 83, 062712 (2011) [4 pages]Quantum Langevin model for exoergic ion-molecule reactions and inelastic processesReceived 31 January 2011; published 23 June 2011 We present a fully quantal version of the Langevin model for the total rate of exoergic ion-molecule reactions or inelastic processes. The model, which is derived from a rigorous multichannel quantum-defect formulation of bimolecular processes, agrees with the classical Langevin model at sufficiently high temperatures. It also gives an analytic description of ion-molecule reactions and inelastic processes in the ultracold regime where the quantum nature of the relative motion between the reactants becomes important. ©2011 American Physical Society URL:
