Web2.1 Triple-axis Reciprocal Mapping. It is well known that the reciprocal lattice vector h of a specific set of lattice planes is defined as a vector in the reciprocal space such that the vector direction is perpendicular to the lattice planes and the magnitude is ∣ h ∣=1/ d, where d is the d -spacing. On the other hand, the basic x-ray ... WebBravais Lattice refers to the 14 different 3-dimensional configurations into which atoms can be arranged in crystals. The smallest group of symmetrically aligned atoms which can be repeated in an array to make up the entire crystal is called a unit cell. There are several ways to describe a lattice. The most fundamental description is known as ...
