Abstract
We report experimental results on resonant electronic Raman scattering in s uperconducting single crystals of Bi2Sr2CaCu2O8+x. The change of excitation wavelength results in a shift of the position for the superconductivity-in duced 2 Delta peak in A(1g) and B-1g symmetries. In addition, in the red-li ght excitation a new Raman peak arises at approximately 130 K in the B-1g s pectra. Various explanations of these effects are discussed.
