Résumé

A spectroscopic method is proposed for removing the azimuth ambiguity intrinsically present in vector magnetograms. The method is based on the idea that the polarization observed in resonance lines (typically formed at the chromospheric level) depends not only on the magnetic field vector, but also on the anisotropy of the radiation field that is illuminating the scattering atoms. An observational scheme is proposed.
