Extract

The results presented here have been obtained with a regular Philips universal spectrometer, equipped with an irradiation tube radically different from those normally used. Since we have previously described this tube in past papers (1) (2) (3), we will therefore only briefly recall its principle.

When starting this research program, our aim was to make possible the analysis of very light elements from sodium to boron, for a regular fluorescence spectrometer, without any modification of the spectrometer itself. As a matter of fact, the tube that we developed enabled us to reach this goal, but, moreover it opened some other possibilities :

  • 1) heavier elements could also be analysed

  • 2) thanks to the very low electric power required by this tube, a portable spectrometer could be built for field use

  • 3) since it allowed a very convenient study of low energy X-rays, we could easily measure energy levels of external electrons and thus study the influence of chemical or crystallographical structure on the X-ray spectrum.
