摘要
A method of obtaining structural information by using wide angle scattering of polarized neutrons from polymers is described. The internal calibration method, where the coherent part is related to the incoherent part of the scattering, with the same correction factors from the same sample, is used. This allows one to get rid of the Debye-Waller factor and the multiple scattering correction and absorption factors, which in this method simply cancel out. Simultaneously, it gives the absolute cross section per formula unit by relating it to its known spin incoherent scattering cross section, as shown for polystyrene.
