| Abstract: |
In this review we first describe briefly the techniques to formulate partial
redistribution (PRD) matrices for polarized line scattering on atoms. These matrices
have to be formulated by either semi-classical or quantum mechanical approach
for the physical process under consideration. We describe the semi-classical
approach that we have been following in our derivations. We then consider
the polarized transfer equation for line formation in three types of
atomic systems and briefly present two numerical methods to solve them.
Finally, a modeling procedure is described to analyze the polarimetric
observations, taking the examples of Ca I 4227 Å line and the
Cr I triplet at 5204-5208 Å. With these examples we demonstrate
that our treatment of PRD is able to correctly account for the
scattering polarization that is caused by various physical processes. |
