WebIn general, a unit cell is defined by the lengths of three axes ( a, b, and c) and the angles ( α, β, and γ) between them, as illustrated in Figure 4.1. 10. The axes are defined as being the lengths between points in the space lattice. Consequently, unit cell axes join points with identical environments.
