1. This is the plane that contains the cylinder axis in reciprocal space . 2. This reciprocal space plane is the " Bragg plane ". 3. The space of wave vectors is called reciprocal space . 4. The Wigner Seitz cell in the reciprocal space is known as the first Brillouin zone. 5. Reciprocal space methods have been used extensively for their ability to evaluate enormous numbers of configurations.6. In crystallography first an approximation of the mapping into reciprocal space is computed that is refined iteratively. 7. Geometrically this means that if the origin of reciprocal space is placed at the tip of "' 8. Where is the del operator in reciprocal space , and force gives a rate of change in crystal momentum: 9. The figure on the left shows a typical fiber pattern of polypropylene before mapping it into reciprocal space . 10. The information is either acquired in direct space or by inverting ( diffraction ) data recorded in reciprocal space .
