Abstract
The pre-edge region of Ti ii-edge polarized XANES spectra in TiO2-rutile is investigated by hull-potential calculations based on the finite-difference method. Both dipolar and quadrupolar transitions are considered. The use o f "non muffin-tin" potential allows a clear interpretation of the pre-edge features. The results are consistent with Full-potential LAPW band structur e calculations, and are also compared with multiple-scattering calculations .
