ON THE INTERACTION OF THE S- ION WITH H-2 AT LOW COLLISION ENERGIES

Potential energy functions have been calculated for the reactions S-(( 2)p) + H-2 --> HS + H- and S-((2)p) + H-2 + HS- + H for low collision energies and collinear geometries. Unlike in the O- + H-2 system, only very flat polarisation minima in the structures S-...H-2 and SH...H- have been found. They are not deep enough to support the formation of a complex in the detachment, in the reactive detachment and in the rea ctive charge transfer processes of the S- + H-2 collision system.
