Abstract: We present results of Raman scattering experiments in differently doped Bi2Sr2(CaxY1−x)Cu2O8+δ (Bi-2212) single crystals. Below Tc the spectra show pair–breaking features in the whole doping range reflecting a dx2–y2 order parameter. In the normal state between Tc and we find signatures for a pseudogap in B2g symmetry which disappear above optimal doping.
