摘要：

Spin-polarized electron-energy-loss spectra have been obtained from Cu(100) and Mo(110) surfaces by use of a polarized primary beam coupled with energy-resolved spin analysis of the scattered electrons. The data reveal strong evidence for inelastic spin-exchange scattering. In particular, a prominent polarization-loss feature evident in the Mo(110) data correlates with the joint density of states available for electron-hole pair excitation. Exchange scattering is observed to decrease rapidly with increasing primary beam energy. © 1990 The American Physical Society.
