Figure 4

Results of the measurements of the elastic incoherent line in a vanadium sample (height 5 mm, diameter 5 mm). The peak energy of each channel is shown with the errorbar corresponding to the FWHM of the Gaussian fit. The different final energies are color-coded: \(2.5\,\)meV (dark blue), \(3\,\)meV (light blue), \(3.5\,\)meV (green), \(4\,\)meV (orange) and \(4.5\,\)meV (dark red). The mean final energy over all \(2\theta \)-channels with the same nominal final energy is shown by the red dotted line. The variations within corresponding \({E}_{f}\)-channels are very small. 5 detectors are missing and the data points are absent in this plot.
