 ## Aufgabe – Reflexe und Gitterebenen
-Laden Sie für diese Aufgabe die Dateien Zinkblende.cif, Diamant.cif und Zinkblende_exp.dat herunter.
+Laden Sie für diese Aufgabe die Dateien Zinkblende.cif, [Diamant.cif](cif files/Diamant.cif) und Zinkblende_exp.dat herunter.
 
 - a)     Importieren Sie in Vesta (https://jp-minerals.org/vesta/en/download.html) die Zinkblende Struktur, erweitern sie die Einheitszellen in x,y und z auf 3 Einheiten und simulieren Sie das Beugungsmuster (PXRD) mit der Wellenlänge von Cu Kalpha lambda=1.54059 Ang. Zeichnen Sie zusätzlich zu den ersten 3 Peaks (2 theta = 28.53 ° , 33.06 ° und 47.45 °) im PXRD jeweils 1 zugehörigen Reflex ein indem sie in Vesta zwei Gitterebenen bei n*d und (n+1)*d. Wählen Sie für diese Ebenen zur besseren Darstellung 5 < n < 20. 
 Exportieren sie das Beugungsmuster für d)
