Abstract

The intensity of the hyperfine doublet of the Cu(I) 324. 8-nm transition was observed as a function of current, fill gas, and fill gas pressure for a new design of hollow cathode lamp incorporating a positive column and an enlarged volume cathode cavity. The intensity ratio of the two components, which reflects the degree of self-absorption, and the flame absorption sensitivity were compared with those of a conventional hollow cathode lamp. Higher intensity, better component ratio, and increased absorption sensitivity were found in the new lamp.
