摘要：

The resonance and incommensurate (IC) peaks in optimally doped high-T-c superconductor YBa2Cu3O6.93 are observed by means of TOF neutron scattering technique in a wide q-E space. The overall dynamical properties around (pi,pi) suggest that the incommensurability delta congruent to 0.1 (at E 36 meV) corresponds to the previous triple-axis measurement. The obtained delta = 0.1 is smaller than that expected from stripe like charge segregation. In the high frequency region, we found the same type of resonance and IC peaks at E = 53 meV.
