Web11 dec. 2016 · If we denote V n the volume of an n -sphere of radius 1, the density of the sphere packing given by the lattice L is. Δ = ( λ 1 2) n V n det L . Often, we will leave out V n. This is δ, or the center density of the lattice. It can be interpreted as the average number of lattice points per unit volume.
