An x-ray photoemission experiment was performed on high-T/sub c/ superconducting Bi-Sr-Ca-Cu-O single crystals with T/sub c/approx.80 K. It is found that Sr and Ca are interchangeable on the lattice sites of the crystal and they are electronically distinguishable. This is consistent with the structure model for the crystal with formula unit Bi/sub 2/(Sr,Ca)/sub 3/Cu/sub 2/O/sub y/. We demonstrate how the distribution of Sr and Ca in the cation sites is determined by x-ray photoemission, which cannot be done by x-ray diffraction.
