Derivation of the radiative transfer equation for line polarization studies in the presence of magnetic field in astrophysics
Résumé
In the preceding paper (063.110), the master equation for the atomic density matrix has been derived in the framework of the impact approximation. In the present paper, the author obtains the spontaneous emission 4-vector and absorption and stimulated emission 4×4 matrices entering the transfer equation for polarized radiation, as functions of the absorbed and emitted radiation polarization tensors, themselves functions of the Zeeman coherences of the atomic density matrix. Line profiles have been ignored.
