Abstract

We have studied the performance of the non local optical potential as developed by Fujikawa, Hatada and Hedin [Phys. Rev. B 62, 5387 (2000)] along the lines of the GW approximation for the photoelectron self-energy, in the case of the absorption spectrum of nickel hydrate (Ni(OH₂)₆). Comparison with the local Hedin-Lundqvist potential [J. Phys. C 4, 2064 (1971)] shows a substantial improvement especially in the low energy region of the spectrum.
