Abstract:	In a recent letter Blumberg and collaborators claim that a non-monotonic dx2- y2 form for the superconducting order parameter is required to explain their Raman scattering measurements in Nd2xCexCuO4. In this comment we show with a simple model calculation that the basis for this conclusion is insufficient. The proposed functional dependence of the gap is neither consistent with their measured spectra nor compatible with other experimental results. Therefore the issue of the superconduing gap in electron-doped systems cannot be considered solved by now.
