SPIN POLARIZATION OF THE RESONANT 2-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 3p63d93p53d10 followed by the superCoster-Kronig transition 3p53d103p63d8l. 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. © 1979 The American Physical Society.
