Description of the most common type of scattering geometries and polarizations.

Symbol Description
Δ(0°) forward scattering
Δ(180°) backward scattering
Δz(90°) depolarized right-angle scattering, where the scattering direction is at right angle with respect to the incident beam and the transmission axis of the linear polarization analyzer, placed on the path of the scattered beam (for ICP) or the incident beam (for SCP), is parallel to the scattering plane (yz)
Δx(90°) polarized right-angle scattering, same as Δz (90°) but the transmission axis of the linear polarization analyzer is perpendicular to the scattering plane
Δ*(90°) magic-angle right-angle scattering, same as Δz (90°) but the transmission axis of the linear polarization analyzer is set at the “magic angle” of ± sin–1(2/3)1/2 ≈ ±54.74° to the scattering plane to remove the contribution from the electric dipole-electric quadrupole (magic angle CID)
