A Potential-splitting approach to multichannel Coulomb scattering: the driven Schrödinger equation formulation II. Comparing an Adiabatic versus a Diabaticrepresentation. Application to the fundamental low-energy mutual neutralisationreaction H+ + H− ! H2 ! H(1) + H(n)
(English)Manuscript (preprint) (Other academic)
In this paper it is demonstrated that the split-potential driven Schrödinger approach to two-body Coulomb multichannel quantum scattering in a diabatic framework presented by us in a previouspaper [XXXXX] also can be formulated within an adiabatic framework. The new formulation of thetheory is numerically realised using finite element discrete variable representation. The method isapplied to a realistic model of the fundamental mutual neutralisation reaction H+ + H−! H2 !H(1) + H(n) described in terms of the seven lowest 1+g electronic states of the H2 molecule. Theobtained cross sections are in good agreement with other methods applied to the same model.
