Abstract : A hollow-cathode carbon resonance lamp was constructed, and the effect of anode configuration, filler gas (helium, argon, and neon), filler-gas pressure, and lamp current on the intensity of emission lines in the region 1560 to 2000 A was studied. The carbon resonance triplet at 1657 A could be obtained with good intensity, as could the carbon line at 1931 A. The spectrum also showed a number of molecular bands, one of which interfered slightly with the carbon resonance line at 1657 A. The bands could be removed, however, by reducing the pressure of the filler gas. (Author)
