description

Durch die Einfuhrung rontgenfluorescenzspektroskopischer Arbeitsmethoden kann die Anwendungsmoglichkeit der Rubidium-StrontiumMethode zur geologischen Altersbestimmung wesentlich vereinfacht und verbreitert werden. Die erforderliche Isotopenanalyse ist durch Untersuchung der Hyperfeinstruktur der Strontiumlinie 4078 A mit relativ einfachen Hilfsmitteln moglich, allerdings erhoht sich dabei die Unsicherheit der Alterswerte um 10–15% bei photographischer bzw. ca. 3% bei lichtelektrischer Messung gegenuber der Verwendung eines Massenspektrometers.
