Associative detachment of H- + H to H2 + e-
Original language description
Using a merged-beams apparatus, we have measured the associative detachment (AD) reaction of H- + H to H2 + e- for relative collision energies up to 4.83 eV. These data extend above the 1-eV limit of our earlier results. We have also updated our previoustheoretical work to account for AD via the repulsive H2- potential energy surface and for the effects above 0.76 eV on the experimental results due to the formation of long-lived H2 resonances lying above the H + H separated atoms limit. Merging both experimental data sets, our results are in good agreement with our new theoretical calculations and confirm the prediction that this reaction essentially turns off for energies above 2 eV. Similar behavior has been predicted for the formation of protoniumfrom collisions of antiprotons and hydrogen atoms.
