Abstract

For near-normal photoemission from ferromagnetic Fe(001) excited by linearly polarized synchrotron radiation, energy-resolved spin polarization and intensity distribution have been measured at 60 eV photon energy. Calculations using a one-step theory of photoemission consistently reproduce. the present spin-resolved data as well as earlier spin-averaged measurements. The quasi-particle exchange splitting deduced from the data is 2 eV. The agreement with band structure calculations is suggested to be coincidental due to a compensation of real and imaginary self-energy corrections.
