This
simulation allows you to "experiment" with Kikuchi lines and to see how they
move in relation to the diffracted spots when the crystal is tilted through small angles.
You can also observe the effect of planar spacing on the Kikuchi lines.
Note: All distances and angles have been exaggerated for clarity.
1.
Under what special condition do the Kikuchi lines intersect the spots?
2. What is the angle between the two Kikuchi lines?
3. When is the excess line brightest?
