Diffraction exercises

This lecture covers exercises related to electron diffraction, focusing on analyzing selected area diffraction patterns to identify crystal structures. The exercises involve determining the crystal system (FCC or BCC), calculating unit cell parameters, and analyzing diffraction ring ratios. The lecture also includes exercises on hexagonal crystal systems, symmetry, and zone axes. Emphasis is placed on understanding systematic absences, diffraction ring radii, and ratios. The exercises aim to enhance students' skills in interpreting diffraction patterns and identifying crystal structures accurately.
