Importance of Angle-dependent Partial Frequency Redistribution in Hyperfine Structure Transitions Under Incomplete Paschen-Back Effect Regime
K. N. Nagendra, K. Sowmya, M. Sampoorna +2
Angle-frequency coupling in scattering of polarized light on atoms is represented by the angle-dependent (AD) partial frequency redistribution (PRD) matrices. There are several lin…
Polarized Line Formation in Arbitrary Strength Magnetic Fields: the case of a two-level atom with hyperfine structure splitting
M. Sampoorna, K. N. Nagendra, K. Sowmya +2
Quantum interference effects together with partial frequency redistribution (PFR) in line scattering produce subtle signatures in the so called Second Solar Spectrum (the linearly…
Atlas of the solar intensity spectrum and its center to limb variation
R. Ramelli, M. Setzer, M. Engelhard +5
The solar limb darkening function is well known and is widely employed in models of the solar atmosphere. However, there has been a lack of systematic spectrally resolved measureme…
Polarized scattering of light for arbitrary magnetic fields with level-crossings from the combination of hyperfine and fine structure splittings
K. Sowmya, K. N. Nagendra, M. Sampoorna +1
Interference between magnetic substates of the hyperfine structure states belonging to different fine structure states of the same term influences the polarization for some of the…
Physics of polarized scattering at multi-level atomic systems
Jan Stenflo
The symmetric peak observed in linear polarization in the core of the solar sodium D line at 5896 Å has remained enigmatic since its discovery nearly two decades ago. One reaso…
The quantum interference effects in the Sc II 4247 A line of the Second Solar Spectrum
H. N. Smitha, K. N. Nagendra, J. O. Stenflo +2
The Sc II 4247 A line formed in the chromosphere is one of the lines well known, like the Na I D_2 and Ba II D_2, for its prominent triple peak structure in Q/I and the underlying…
