Abstract

Wavelengths in the first and second spectra of ⁸⁶Kr are reported. Included are results of observations in the nonphotographic infrared region and conventional intercomparisons by use of Fabry–Perot interferometers in a vacuum, with the primary wavelength standard at 6057 Å, originating in a microwave-excited electrodeless discharge operated at the triple point of nitrogen. The wavelengths are in the region between 3623 and 28 663 Å. All wavelengths of these spectra that have been reported at recent meetings of the Optical Society of America or in internal reports are included.
