Linear Density
Linear density is the number of lattice points or repeat distances per unit length in a particular direction. Since aluminum is FCC, along the [110] direction (face diagonal in the top plane) there
are two lattice points (atoms, not counting the starting point) encountered. (see Figure 3-13, page 52).
