In general, a number of independent experimental observations confirm that the rt-plasma is due to a novel reaction of atomichydrogen. As for atomichydrogen, the lifetime of atomic nitrogen in its ground state is relatively long and sufficient to permit the reaction with carbon vapour. In contrast to the atomichydrogen lines, no broadening was observed in helium or argon lines. This was the thermal decay time of the filament that dissociated molecular hydrogen to atomichydrogen. The fullerene-like structures in carbon dust may be responsible for instance for the formation of molecular hydrogen from atomichydrogen by an enhanced surface chemistry mechanism. The observed plasma formed from atomichydrogen generated at a tungsten filament that heated a titanium dissociator and one of potassium, rubidium, caesium and their carbonates and nitrates. Pickling with acids (e.g. sulphuric or chloric acid) produces atomichydrogen and can penetrate into the steel structure and make it brittle.

Under normal conditions, the atomichydrogen will combine at the metal surface to create hydrogen gas, which can not penetrate the metal.

Just as an arc flame (as in atomichydrogen welding), it can be moved from one place to another and can be better controlled.

The "ion mass spectrometers" measured the concentrations of different types of ions in the topside ionosphere, principally atomichydrogen, helium, nitrogen, and oxygen.

Susceptible alloys, especially steels, react with hydrogen sulfide, forming metal sulfides and atomichydrogen as corrosion byproducts.
