Interactions of H and H/sup -/ with He and Ne

Journal Article · · Phys. Rev., A; (United States)
Potential energies have been computed for the ground states of HeH, HeH/sup -/, NeH, and NeH/sup -/ using the configuration-interaction method. The HeH/sup -/ potential curve is found to cross into the HeH continuum at R=2.70a/sub 0/ with a threshold energy of 1.34 eV. In contrast, the NeH/sup -/ state is found only to merge with the NeH continuum at Rapprox. =2.25a/sub 0/ at an energy of 2.7 eV. These calculations suggest the threshold-energy collisional electron detachment for HeH/sup -/ can be best described by the complex potential method, while the NeH/sup -/ detachment mechanism is more akin to a charge transfer to the continuum process.
