Abstract The magnetic neutron scattering cross section in a crystal YBa2Cu3O6.5(T c =50 K) has been measured for energies between 4.5 meV and 15 meV and temperatures between 10 K and 275 K. From these data we extract the generalized susceptibility integrated around the (π, π) position $$I(\omega ,T) = \int\limits_{(\pi ,\pi )} {dq\operatorname{Im} \chi (q,\omega )_T .}$$ These data are combined with those at 8.3 and 33.1 meV from a previous study. It is found thatI(ω, T) exhibits the simple temperature scaling form found previously in La2−x Sr x CuO4. Specifically, in YBa2Cu3O6.5,I(ω, T)=I(ω, 0)2/πtan−1 (ω/0.9T). Implications of this behavior for the d.c. and infrared conductivity are discussed.
