摘要：

We show that the anomalous temperature T dependences at low frequencies omega observed in neutron measurements of the structure factor S(q,omega) are compatible with a d(x2-y2) pairing state. We further demonstrate that convincing verification of this anisotropic pairing also requires the observation of a q dependence which, in low-T neutron data, differs significantly from that above T(c). In the absence of such evidence, establishing the existence of the d(x2-y2) State remains problematical.
