Der Arbeitsgruppe von Prof. Anton Zeilinger in Wien ist es gelungen, einen Atomstrahl aus Fullerenen zu erzeugen und diese an einem extrem feinen Gitter zu beugen.
As is the case with electron microscopy, the method is generally based on the concept of an electron beam being directed at an object and diffracted as a result.
The beam of C60 molecules is extracted at approx. 600 ° C from an oven, collimated by two slits and diffracted on a grating. Finally the scattered " balls " are optically stimulated to emit radiation and thus can be detected.
Ein Molekülstrahl aus C60 wird in einem Ofen bei einer Temperatur von ca. 600 ° C extrahiert, durch ein Doppelschlitzsystem kollimiert, dahinter auf ein Gitter gerichtet, an dem der Strahl gebeugt wird und schließlich mittels optischer Anregung der gestreuten " Bälle " indirekt nachgewiesen.
Die Winkelverteilung von Licht, das an einer Probe reflektiert, gestreut oder gebeugt wurde, können wir mit einem Goniometeraufbau auf einem optischen Tisch vermessen.
