Spin Polarization of the Resonant Two-Hole Bound State in Ni Photoemission

We calculate the spin polarization of the 6-eV resonant satellite in Ni $3d$-band photoemission. The satellite is identified with the 3d⁸ configuration, and the resonant process involves the absorption 3p⁶3d⁹→3p⁵3d¹⁰ followed by the super---Coster-Kronig transition 3p⁵3d¹⁰→3p⁶3d⁸εl. The spin-up (majority) to spin-down (minority) intensity ratio is found to be approximately 4: 1 for the resonant process, whereas nonresonant Auger decay is found to be essentially unpolarized.
