Название: Chemical Analysis by X-Rays and Its Applications
Автор: von Hevesy G.
For a long time the line spectrum of an element has been used as a means for its identification and, more recently, spectroscopic methods have been developed not only for qualitative but also for quantitative chemical analysis. If the optical spectrum has been found so useful in the practical problems of analysis, it is only to be expected that the X-ray spectrum should prove capable of being similarly employed.
