Abstract

Vacuum wavelengths are given for the Hg¹⁹⁸ 2537- and 3132-A lines and the Kr⁸⁶ 6013- and 5651 A lines, referred to the Kr⁸⁶ primary standard line 6057 A. The light sources were an Hg¹⁹⁸ atomic-beam and a Kr⁸⁶ hot-cathode lamp. A vacuum Fabry-Perot interferometer was employed for the measurements. The wavelength of the Hg¹⁹⁸ 3132 A line was also determined by using the Hg¹⁹⁸ 2537-A line as the reference standard. The accuracy of measurement of the Hg¹⁹⁸ lines is about a factor of 5 higher than that of the Kr⁸⁶ lines.
