The observation of spin-dependent photoelectron diffraction using circularly polarized x rays is reported for Fe films on Cu(001). Circularly polarized x rays produce spin-polarized photoelectrons from the Fe 2[ital p] doublet, and intensity asymmetries in the 2[ital p][sub 3/2] level are observed. Fully spin-specific multiple-scattering calculations reproduce the experimentally determined energy and angular dependences. An analytical procedure is introduced which removes exchange shift contributions to the Fe 2[ital p] asymmetry, and focuses instead upon intensity variations due to spin-dependent diffraction.
