Observation of enhanced rate coefficients in the H₂⁺+H₂→H₃⁺+H reaction at low collision enrgies. Allmendinger, P., Deiglmayr, J., Höveler, K., Schullian, O., & Merkt, F. The Journal of Chemical Physics, 145(24):244316, 2016. ![Observation of enhanced rate coefficients in the H₂⁺+H₂→H₃⁺+H reaction at low collision enrgies [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex The energy dependence of the rate coefficient of the H2++H2→H3++H reaction has been measured in the range of collision energies between kB 10K and kB⋅300mK. A clear deviation of the rate coefficient from the value expected on the basis of the classical Langevin-capture behavior has been observed at collision energies below kB⋅1K, which is attributed to the joint effects of the ion-quadrupole and Coriolis interactions in collisions involving ortho-H2 molecules in the j = 1 rotational level, which make up 75% of the population of the neutral H2 molecules in the experiments. The experimental results are compared to very recent predictions by Dashevskaya et al. [J. Chem. Phys. 145, 244315 (2016)], with which they are in agreement.
