Abstract
Although the low-frequency electronic Raman response in the superconducting state of the cuprates can be largely understood in terms of a d-wave energ y gap, a long-standing problem has been an explanation for the spectra obse rved in the A(1g) polarization orientations. We present calculations which suggest that the peak position of the observed A(1g) spectra is due to a co llective spin fluctuation mode.
