| The
cubic lattice is one of the seven symmetry groups for the Bravais space
lattice. The diagram shows the three unit cells associated with this group.
For this lattice: a = b = c, a = b = g = 900.
The Primitive cell (P) has fractional lattice points only at the cube corners, for a total of one lattice point per cell. The Face-centered-cubic cell (F) has fractional lattice points at the cube corners and at the center of each cube face for a total of four lattice points per cell. The Body-centered-cubic cell (I) has fractional lattice points at the cube corners and an additional lattice point at the cube center for a total of two lattice points per cell. |
