An experimental verification of neutron multiple scattering calculations in vanadium

A method is described for experimentally measuring the neutron multiple scattering in four vanadium samples of different geometry by means of the polarization analysis technique. The spin-dependent scattering cross section of ⁵¹V provides a much more stringent test of multiple scattering than is possible by intensity measurements, and the experimental results are shown to be in excellent agreement with theoretical calculations of the multiple scattering carried out by a Monte-Carlo procedure.
