Some New Aston Bands in Hydrogen

Broad nonintegral mass bands at the 0.66- and 0.75-u mass positions appear in the hydrogen mass spectrum at high pressure (${10}^{-4\mathrm{}}$ Torr). A primary peak is also observed at the 1.5-u mass position. These Aston bands and mass peak may be interpreted as resulting from the creation and collision-induced reactions of the ${\mathrm{H}}_3^{++}$ ion, which would be formed in a surface reaction between ${\mathrm{H}}_3^{+}$ and adsorbed hydrogen.
