In this chapter and the following two, we will discuss two special cases of electron diffraction. We’ll see that incoherently scattered, divergent beams of electrons give rise to paired arrays of lines in SADPs, known as Kikuchi patterns. In the next two chapters, we will form DPs with a convergent rather than a divergent (or, as in the previous chapter, parallel) beam. These two techniques have a lot in common. In the first, the electrons are initially being scattered by the atoms in the crystal so that they ‘lose all memory of direction’ and may also lose energy.
