Evidence for an anisotropic superconducting gap in the electron doped material that is consistent with a dx(2)-y(2) pairing state is presented. It is shown that despite the strong differences between the p- and n-type compounds in the larger scale electronic structure, their superconductivity share the same symmetry and is therefore possibly of similar origin.
