The formation of a Zeeman-multiplet by noncoherent scattering and true absorption in a Milne-Eddington atmosphere is considered assuming a homogeneous magnetic field and complete depolarization of the atomic line levels. The transfer equation for the Stokes parameters is transformed into a scalar in
Theoretical line contours calculated for fixed values of the line constants and a given model atmosphere show an increase of the Stokes parameters Q, U, and V but a decrease of I if the portion of non-coherent scattering increases. These effects increase from the centre of the solar disk to the limb
The transfer equations for the Stokes parameters in the presence of magnetic field and under the hypothesis of LTE are derived in an original way by the use of density matrix techniques. The results are substantially the same as those previously obtained by other authors. We finally compare our res
