To study the superconducting-gap symmetry in electron-doped HTSC, we performed a high-resolution ARPES on Pr 0.89 LaCe 0.11 -CuO 4 (optimally-doped, T c = 26 K). Obtained momentum dependence of the superconducting gap is basically consistent with the d x 2 Γ€y 2 -wave symmetry, but obviously deviates
