WebFigure 12.6.6: The General Features of the Seven Basic Unit Cells. The lengths of the edges of the unit cells are indicated by a, b, and c, and the angles are defined as follows: α, the angle between b and c; β, the angle between a and c; and γ, the angle between a and b. Cubic: a = b=c, alpha= beta=gamma = 90 degrees.
