| Abstract: | The scattering phase matrices for forbidden lines in the presence of an external magnetic field are derived. The particular cases of E2 (electric quadrupole) and the (magnetic quadrupole) forbidden line transitions are considered. The quantum electrodynamical approach employed in the calculations is discussed. As an example, compact analytical expressions for the case of a multiplet ($J=0 \rightarrow 2 \rightarrow 0$ scattering transition) are presented. The Rayleigh scattering phase matrix for some forbidden lines in the non-magnetic case is also given. The Stokes profiles produced in a single scattering of forbidden line radiation for an unpolarized beam of incident radiation, are shown in the week-field limit (Hanle scattering), up to the strong field limit (Zeeman scattering), covering also the intermediate field strength regime of Hanle-Zeeman scattering. |
