Formation of H2+ and H3+ in energetic highly-charged-ion collisions with NH3
Abstract
The dissociation of NH3 is studied using energetic H + and Arq + (q =1 ,8 ) ions. The multi-ion coincidence technique along with the time- and position-sensitive measurements of the recoil ions allows us to distinguish different dissociation channels involving the rearrangement of hydrogen atoms. It is observed that the bond dissociation of NH3x + (x =3 -5 ) occurs in a concerted manner and nonplanar dissociation exists. Our results indicate a competition between the bond-rearrangement and Coulomb repulsion processes in NH3x + . Ab initio intrinsic reaction coordinate calculations are performed to understand the bond-rearrangement process in NH32 + .
