X Ray Wavelengths PDF Download

Excerpt from X-Ray Wavelengths and X-Ray Atomic Energy Levels In principle any x-ray line could be chosen and assigned an arbitrary value; for example, Cu Kal 1000000 Cu unit. Then in every calculation of the properties of matter involving knowledge of atomic dimensions, a conversion. Factor would be required. Since the vast majority of such calculations do not attain an accuracy better than 10 ppm, this.procedure appears to. Be unnecessary, provided, however, an absolute wavelength standard can be defined whose wavelength in centimeters or: Angstroms is known Within a few ppm. Oi course, -for the most precise calculations, e.g., atomic constants, a conversion factor differing from unity by a few ppm will be required, and this factor will change slightly as the accuracy of absolute zeray wavelength measurements is increased.
