Kr 86 AND Hg 198 WAVELENGTH STANDARDS

Abstract

New values are given for the vacuum wavelengths of six lines of Kr 86 and five lines of Hg 198 in the visible spectrum. The wavelengths were referred to the Kr 86 primary standard line, 6057.80211, by a series of very careful measurements over a period of several years. The accuracy with which wavelengths can be compared by present methods is discussed at some length.
