Solution 1. WebFiber diffraction is a subarea of scattering, an area in which molecular structure is determined from scattering data (usually of X-rays, electrons or neutrons).In fiber diffraction the scattering pattern does not change, as the sample is rotated about a unique axis (the fiber axis).
