A critical comment was made to the electron energy-loss spectroscopy [Z. Phys. B-Condensed Matter 75, 421 (1989)] which questioned n-type superconductivity in Nd2-xCexCuO4. Comparative oxygen-K absorption and oxygen 1 s photoemission spectroscopies for Nd2-xCexCuO4 and Bi2Sr2CaCu2O8 have shown that these two superconductors are classified into two different categories.
