Representative Q-sliced scattering functions S(Qfix, ω) obtained at different temperatures. The Qfix and temperature details are as follows: (a) 1.00 ± 0.30 Å−1 and 180 K, (b) 1.10 ± 0.15 Å−1 and 230 K, (c) Q = 1.15 ± 0.10 Å−1 and 280 K, and (d) Q = 1.625 ± 0.275 Å−1 and 430 K. An energy scan window range between −30 and 60 µeV is selected for each case. Open circles represent the observed functions and lines represent fitting functions for the observed ones; thin black lines are the resolution function R, long- and short-dashed lines are the Lorentz functions L(Γ1, ω) and L(Γ2, ω), respectively, thick grey lines are the background BG, and thick black solid lines are the sum of all these functions. The resolution function was convoluted in the energy scan window range between −30 and 30 µeV. |
