ATLAS OF THE SPECTRUM OF A PLATINUM NEON HOLLOW-CATHODE REFERENCE LAMP IN THE REGION 1130-4330 ANGSTROM

The spectrum of a platinum hollow-cathode lamp containing neon carrier gas was recorded photographically and photoelectrically with a 10.7 m normal-incidence vacuum spectrograph. Wavelengths and intensities were determined for about 5600 lines in the region 1130-4330 angstrom. An atlas of the spectrum is given, with the spectral lines marked and their intensities, wavelengths, and classifications listed. Lines of impurity species are also identified. The uncertainty of the photographically measured wavelengths is estimated to be +/-0.0020 angstrom. The uncertainty of lines measured in the photoelectric scans is 0.01 angstrom for wavelengths shorter than 2030 angstrom and 0.02 angstrom for longer wavelengths. Ritz-type wavelengths are given for many of the classified lines of Pt II with uncertainties varying from +/-0.0004 to +/-0.0025 angstrom. The uncertainty of the relative intensities is estimated to be about 20%.
