K-absorptiespectra van Cr, Mn en Fe in de metalen en in verbindingen

In Chapter I an introductory survey is given of early experimental work on the fine structure near x-ray absorption edges of elements in crystalline solids and polyatomic molecules and its successful wave-mechanical interpretation by Kronig. The x-ray spectrometers with a much higher resolving power, developed during the last decennia, made it possible to investigate the fine structure close to the edge in more detail. To account for these fluctuations one needs the theoretical calculations of the density of empty states near the Fermi limit following the methods developed by Wigner, Seitz, Slater a.o. ....
