TheXYZ-Difference Method with Polarized Neutrons and the Separation of Coherent, Spin Incoherent, and Magnetic Scattering Cross Sections in a Multidetector

Abstract

Equations are derived for the polarization analysis in a multidetector to separate coherent, spin incoherent, and magnetic scattering using three-dimensional analysis or the xyz-difference method. Then the conditions for the magnetic guide fields to rotate the polarization into the three directions x, y, and z are discussed on the basis of the existing instrument D7 at the ILL in Grenoble.
