Spin and the Complementary Worlds of Electron Position and Momentum Densities

  • Jonathan A. Duffy
  • Malcom J. Cooper


The extent to which the electron momentum density and spin density can be studied through the Compton effect is outlined. The isolation of a measurable spin-dependent effect in ferromagnets with helically-polarized high energy synchrotron radiation is described within the impulse approximation. The interpretation of directionally dependent data and the reconstruction of the full three dimensional spin density is illustrated by reference to recent results. The Compton method is compared and contrasted with the study of spin and orbital magnetization in non-resonant x-ray diffraction experiments.
