Description
In mutual neutralisation, two oppositley charged ions collide, an electron is tranfered and the colliding pair ends up in neutral fragments. In the Born-Oppenheimer approach the electronic structure of the molecule is solved for in an initial step, and the nuclear motion is solved for in a second step giving relevant scattering information such as cross section, differential cross section and branching ratios for the reaction. The radial non-adiabatic coupling is the dominant, driving mechanism in mutual neutralization, but other couplings mechanisms may also be significant. Here, the additional couplings mechanisms of rotational coupling, spin-orbit coupling, electronic coupling and asymptotic non-adiabatic coupling are studied, and applied to the mutual neutralization in Na$^+$ + I$^-$ and H$^+$+H$^-$ collisions.
