Abstract:

Laser absorption techniques have been developed for the measurement of densities of H2 C 3 Pi sub u metastable densities in H2 electrical discharges. Using this technique and a modulated discharge we have found that the metastable density is proportional to discharge current density for current densities up to 10 Asq cm. By using a pulsed laser to destroy th metastables we have obtained preliminary measurements of the metastable lifetime as a function of H2 density. Keywords hydrogen, electrons, radiation, excitation coefficient, fluorescence, excited states.
