Geometry considered for computing the polarization diagrams shown in Figure 6. β is the angle between the magnetic field vector and the scattered beam. The incident radiation is characterized by (θ′, χ′) = (90°, 0°) and the scattered radiation by (θ, χ) = (β, 90°). The magnetic field inclination is θ_B = 0° and its azimuth is χ_B = 0° (magnetic reference frame).
