Abstract Spin-resolved x-ray photoelectron spectroscopy (SRXPS) studies are reported of a high-binding-energy satellite associated with Fe 3s photoemission. The satellite is found to possess a complex spin polarization with three distinct components. Two majority-spin ({up_arrow}-spin) components are observed with binding energies 111.0{plus_minus}0.5 and 123.4{plus_minus}0.5 eV. These majority-spin satellites are accompanied by a minority-spin ({down_arrow}-spin) peak located at 118.6{plus_minus}0.5 eV binding energy. The spin analysis, combined with electron-energy-loss measurements, indicate that these 3s satellites do not result from plasmon excitation. Comparison of the SRXPS data with theory for the atomic Fe 3s spectrum suggests the majority-spin satellites are caused by final-state configuration interaction between the 3s{sup 1}3p{sup 6}3d{sup 7} hole state and the nearly degenerate 3s{sup 2}3p{sup 4}3d{sup 8} configuration. The origin of the minority-spin satellite component is not understood. {copyright} {ital 1997} {ital The American Physical Society}
