Resonance-line polarization. Pt. 1
Description
A non-LTE theory for resonance-line polarization due to coherent scattering is developed for the magnetic field-free case. The equation of radiative transfer for the Stokes vector is written in a form analogous to the formalism normally used for the well-explored non-LTE case of isotropic scattering and complete redistribution. This makes it possible to apply the powerful numerical methods developed in the past to solve non-LTE problems and extend them to calculate the transport of polarized light for multi-level atoms.

Abstract (German)
Es wird eine nicht-LTE-Theorie der Resonanzlinienpolarisation durch kohaerente Streuung fuer den Fall ohne Magnetfeld entwickelt. Die Strahlungstransfergleichung fuer den Stokes-Vektor wird in einer Form gegeben, die in Analogie zu dem bereits gut erforschten nicht-LTE-Fall der isotropen Streuung und vollstaendigen Umverteilung steht. Dadurch wird die Anwendung der in der Vergangenheit entwickelten wirksamen Rechenverfahren zur Loesung von nicht-LTE-Problemen ermoeglicht, und sie koennen fuer die Berechnung des Transports von polarisiertem Licht fuer Mehrniveauatome erweitert werden.
