Measurements of balmer line radiation from self-sustained Townsend discharges in hydrogen

Summary

Absolute radiation intensities of the Hα and Hβ lines emitted from self-sustained Townsend discharges in hydrogen have been measured by means of interference filters and a photomultiplier tube. The radiation intensity was in all cases found to be proportional to the discharge current, i.e., the radiation has been produced in single encounter electronic excitation processes. The excitation coefficient, corrected for quenching of the radiation, has been determined absolutely forE/p=65–250 v/Torr×cm. Finally, some possible production mechanisms have been discussed.
