With the use of X-ray excited polar core-level and valence-band photoe
lectron-diffraction patterns (XPED) and corresponding energy distribut
ion curves from TiO2(110) (rutile) along various azimuths in the surfa
ce plane, projected partial densities-of-states of the constituents in
the valence band have been extracted. The results obtained from this
angle-resolved method do not depend on the electron exit angle and see
m to be a good measure for state densities of the bulk. A comparison w
ith electronic structure calculations is given.
