Figure 2
The evolution of rocking curves with temperature for lowest (top panel) and highest (bottom panel) temperatures. The incidence angle θ is given as the deviation from the Bragg angle determined by accounting for the shift due to refraction of the incident beam at the entrance into the crystal. Blue crosses indicate the angular positions where the Mössbauer spectra were measured. The red dashed line shows the optimal conditions for SMS operation (see text). |
