Abstract
The emission spectrum of cerium was recorded on the 1m Fourier transform spectrometer (FTS) at the National Solar Observatory, Kitt Peak, AZ., using a 140Ce electrodeless discharge lamp (EDL) as a source. The frequency range 4,000 to 27,600 cm-1 was covered in two runs while maintaining the EDL parameters as constant as possible. Large UV diodes were used as detectors for the 9,100 to 27,600 cm-1 range and In/Sb detectors were used for the 4,000 to 14,300 cm-1 range. The instrument was intensity calibrated for both ranges using standard lamp scans. A multiplication factor obtained from the overlap region was applied to bring the two regions to the same intensity scale.
