Figure 4
The neutron scattering intensity from catalase as recorded by the area detector of D22. The large peaks on the left and right side of the beamstop are part of the primary beam. It is the neutron beam polarizer about half a metre upstream of the diaphragm at the sample which slightly enlarges the beam in the horizontal direction. The red lines denote the limits of the spherical averaging of the scattering intensity (see Fig. 7).
