Polarization phase matrices for radiation scattering on atoms in external magnetic fields: The case of forbidden transitions in astrophysics (2008)

Oo, Yee Yee, San, Phyu Phyu, Sampoorna, M., Nagendra, K. N., Ramachandran, G.

Using a quantum electrodynamical approach, we derive the scattering phase matrices for polarized radiation involving forbidden line transitions and in the presence of an external magnetic field. The...

Scattering polarization in the presence of magnetic and electric fields (2007)

Yee Yee Oo, Sampoorna, M, Nagendra, K. N, Ananthamurthy, S, Ramachandran, G

The polarization of radiation by scattering on an atom embedded in combined external quadrupole electric and uniform magnetic fields is studied theoretically. Limiting cases of scattering under...

Photodisintegration of polarized deuterons at astrophysical energies (2006)

Ramachandran, G, Yee Yee Oo, Shilpashree, S. G

A model independent irreducible tensor formalism, developed earlier for np fusion, is extended to discuss photodisintegration of the deuteron at astrophysical energies. It is shown that target...

Oo, Yee Yee, Nagendra, K. N., Ananthamurthy, Sharath, Ramachandran, G.

The polarization of radiation by scattering on an atom embedded in combined external quadrupole electric and uniform magnetic fields is studied theoretically. Analytic formulae are derived for the...

Polarization of line radiation in the presence of external electric quadrupole and uniform magnetic fields: II. Arbitrary orientation of magnetic field (2005)

Yee Yee Oo, Nagendra, K. N, Ananthamurthy, S, Sirsi, S, Vijayashanka, R, Ramachandran, G

In continuation of our earlier investigation (referred to hereafter as part I) where we considered the mathematically simple case of magnetic field orientation along the Z-axis of the principal axes...

Polarization of line radiation in the presence of external electric quadrupole and uniform magnetic fields (2004)

Yee Yee Oo, Nagendra, K. N, Ananthamurthy, S, Vijayashankar, R, Ramachandran, G

The polarization of emission lines formed in a medium immersed in external electric and magnetic fields is studied. The electric field is assumed to be quadrupolar in nature, while the magnetic field...
