Abstract Type : Oral Abstract Category : Sun and the Solar System Abstract : Paschen-Back effect (PBE) occurs when the magnetic field produces a splitting which is of the order of or greater than the separation between the unperturbed atomic levels. The polarization content in the emergent radiation from the Sun is modified by the PBE. In this work, we apply the recently developed theory of PBE in atomic fine and hyperfine structure states including the effects of partial frequency redistribution to the case of Li {\sc i} 6708 \AA{} doublet. We explore the signatures of PBE in a single scattering of the incident radiation by the atom and their applicability for the solar magnetic field diagnostics. |
