Free-electron-like Stoner excitations in Fe

Abstract
An analysis of spin-polarized electron-energy-loss experiments in Fe is described which (1) identifies the contribution of d-electron Stoner excitations, the usual type of Stoner excitation, (2) suggests that free-electron-like Stoner excitations are more probable than d-electron Stone excitations, and (3) indicates that exchange events involving large energy losses are as likely as direct scattering.
