An ab initio computed potential energy surface is employed to
evaluate the interaction of the OH+(3Σ -) molecule with
4He(1S) atom and an analytic fitting of the raw points is
directly employed in quantum scattering calculations at ultralow
collision energies. The Hund's case (b) chosen to handle the
spin-rotation coupling allows to extract from the numerous inelastic
cross sections the relative importance of pure “spin flip" vis-à-
vis rotational cooling cross sections. The final rates of all the
above processes as a function of the initial |N〉 state are
analysed in detail and possible propensity rules are discussed. 相似文献
