Gianturco (2018) Rotational ‘cooling’ and ‘heating’ of OH+(3Σ−) by collisions with He: quantum dynamics revealing propensity rules under ion trap conditions, Molecular Physics, 116:19-20, 2686-2697, DOI: 10.1080/00268976.2018.1442597 0026-8976 http://hdl.handle.net/10366/146608 10.1080/00268976.2018.1442597 1362-3028 [EN]Multichannel scattering calculations are presented for the low-energy collisions of the OH+ cation and He atoms, using an ab initio evaluation of the interaction potential, which had been obtained in earlier work, and a time-independent, multichannel treatment of the quantum dynamics carried out in this study using our in-house scattering code ASPIN. Given the presence of spin-rotation coupling effects, within an essentially electrostatic formulation of the interaction forces with He atoms in the trap, the ensuing propensity rules which control the relative size of the state-changing cross sections and of the corresponding inelastic rates, also computed at the most likely temperatures in an ion trap, are presented and analysed in detail. application/pdf eng Molecular Physics Attribution-NonCommercial-NoDerivatives 4.0 Internacional http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Cooling rates in traps Quantum scattering calculations Rotationally inelastic dynamics Quantum Dots 2210 Química Física puntos cuánticos Rotational ‘cooling’ and ‘heating’ of OH+(3Σ−) by collisions with He: quantum dynamics revealing propensity rules under ion trap conditions info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://doi.org/10.1080/00268976.2018.1442597 Molecular Physics 116 19-20 2686 2697
