Intercomparison of Micrometer, Nanometer and Picometer Wavelengths

Abstract

We have undertaken to arrange a group of wavelength measurements in such a way as to assure that each is well tied to a standard wavelength common to all. [This wavelength is, in fact, the 606 nm emission from 86Kr at the N2 triple point which is the defined wavelength, although such a pedigree is unnecessary in this story.] By coordination with some aspects of the work of Earnest Kessler on the Rydberg (reported at this meeting) and of Horace Bowman and Randall Schoonover on density we plan to tie together the Rydberg (R), Avogadro’s constant (No), the electron’s Compton wavelength (λc = h/mc), the scale of γ-ray wavelengths (eg, the 411 keV emission from Au) and the scale of x-ray wavelengths (as might be characterized by a value for ∧, the x-ray-metric conversion factor).
