Fig. 79: Energy dependence of the fluorescence (a) and the resonance at three different magnetic reflections (b) at the L₃ edge of samarium. Dipolar and quadrupolar resonances depend on the wave-vector transfer in a different way. The vertical line shows the position of the absorption edge. The solid lines in (a) and (b) are the result of a calculation using the model density of states (c).
