Figure 4
The DiffXRD transmission signal obtained for ΔT = 6 K in the energy region of the glitch shown in Fig. 3 (dashed line). The difference between a pair of Gaussians of width and height determined by the fit in Fig. 3, and offset in energy relative to one another, are fitted to the feature (solid line), the energy offset being related to the fractional change in lattice spacing. |
