Cc. Kao et al., X-RAY RESONANT RAMAN-SCATTERING IN NIO - RESONANT ENHANCEMENT OF THE CHARGE-TRANSFER EXCITATIONS, Physical review. B, Condensed matter, 54(23), 1996, pp. 16361-16364
An energy loss feature with energy transfer close to the anion-to-cati
on charge-transfer energy of NiO is observed in the inelastic-x-ray-sc
attering spectrum as the incident x-ray energy is tuned through the Ni
K absorption edge of NiO. The inelastic-scattering cross section show
s large resonant enhancement and strong incident energy dependence. Th
ese observations are interpreted using a configuration-interaction clu
ster model of NiO.
