Abstract = {{We report on an x-ray absorption and resonant photoemission study on
   single crystals of the high-T-c cuprates La2-xSrxCuO4 and
   Nd2-xCexCuO4-delta. Using an intrinsic energy reference, we find that
   the chemical potential of La2-xSrxCuO4 lies near the top of the La2CuO4
   valence band whereas in Nd2-xCexCuO4-delta it is situated near the
   bottom of the Nd2CuO4 conduction band. The data clearly establish that
   the introduction of Ce in Nd2CuO4 results in electrons being doped into
   the CuO2 planes. We infer that the states closest to the chemical
   potential have a Cu 3d(10) singlet origin in Nd2-xCexCuO4-delta and a
   3d(9) (L) under bar singlet origin in La2-xSrxCuO4.}},
