Momentum transfer (Q) dependence of the inelastic contribution to the total scattering for the indicates samples and temperatures, expressed as a percentage of the integrated total intensity over an energy range of [−20, 120] meV for (a) PMMA and (b) Tempax. Note the highest momentum transfer in each case corresponds to the first minimum of the structure factor and in included for reference only: all practical resolution measurements are at momentum transfers close the SF maximum. See also Fig. 8 where the I(Q, ω) plane is shown. |
