摘要：

We analyze neutron experiments on YBa2Cu3O6+x at various stoichiometries in the superconducting state, within the context of a bilayer theory that yields good agreement with the normal state Cu NMR and neutron data as a function of omega, q, and T. A d-wave superconducting state exhibits peaks at q = (pi,pi,pi) and sharp maxima as a function of omega, at twice the gap frequency. This behavior may have been observed experimentally. The counterpart behavior for other choices of order parameter symmetry, as well as for another cuprate La1.85Sr0.15CuO4, is discussed.
