Description
We present a generalized frequency redistribution function for the
polarized two-term atom in an arbitrary magnetic field. This result is
derived within a new formulation of the quantum problem of coherent
scattering of polarized radiation by atoms in the collisionless regime.
The general theory, which is based on a diagrammatic treatment of the
atom-photon interaction, is still a work in progress. However, the
results anticipated here are relevant enough for the study of the
magnetism of the solar chromosphere and of interest for astrophysics in
general.

Magnetic fields pervade all astrophysical plasmas and govern most of the variability in the Universe at intermediate time scales. They are present in stars across the whole Hertzsprung-Russell diagram, in galaxies, and even perhaps in the intergalactic medium. Polarized light provides the most reliable source of information at our disposal for the
