X-ray was discovered in 1895 by W.K. Rontgen. After its discovery, studies of this radiation were expanded when in 1912 Laue and Friedrich found that the atoms in crystals diffracted... 

It was exactly this purism that was the guiding principle for the choice of researchers presented. This is already clear with the example of Wilhelm Rontgen (1845-1923 first Nobel Prize for physics 1901). Rontgen made no direct contribution to... 

The guiding principle that was decisive in the choice of Rontgen is also true for Antoine H. Bec-guerel (1852-1908 Nobel Prize for physics 1903 together with Pierre and Marie Curie). His discovery of radioactivity was not only the basis for the unraveling of new elements (radium and polonium by the Curies). Radioactivity and its phenomena became a universal tool that provided succeeding chemists and physicists with insight into the world of atoms.

Eine direkte Messung des Rontgen-Emissionsspektrums existiert bisher nicht, doch werden vielfach beim radioaktiven Zerfall die K-, L-und M-Serie angeregt. Rogosa und Peed (167) sowie Day (62) konnten auf diese Weise folgende Rontgenemissionslinien des Americiums messen ... 

Von alien aufgefiihrten Californiumverbindungen wurden Rontgen-diagramme aufgenommen, doch ist liber deren Ausdeutung bisher noch nichts veroffentlicht worden. 

Eine Reihe anderer Autoren hat andere Wege zur Unterdruckung des Rontgen-effekts beschritten, doch wird gegenwartig die Rohre von Alpert wohl allgemein beniitzt.

Two fundamental discoveries about the structure of the atom and electromagnetic radiation also occurred during this period and provided a foundation for instrumentation that would be fundamental in furthering our understanding of soil chemistry. One was the discovery of X-rays, also sometimes called Rontgen rays, discovered in 1895, by W. Rontgen [24], The second was made by J. J. Thomson in 1912. He observed positive rays and described how these could be used to identify compounds and elements. Subsequently, he presented a clear description of the process in 1913. This led to the development of mass spectrometry [25],...
