Abstract

• Degree of polarization of scattered line radiation in the presence of the magnetic field was investigated. The Stokes parameters of the scattered radiation incident on an arbitrary polarized atom in any given arbitrary direction were calculated. It was considered that the polarization of scattered line radiation from an upper atomic level with angular momentum Ju = 3/2 to a lower atomic level with angular momentum J = 1/2 transition. This line has transition of both type electric dipole transition and magnetic quadrupole transition. Only the electric dipole transition was considered for upper and lower atomic levels having different parities. The degree of linear polarization of scattered radiation in the presence of weak external magnetic field was calculated. In this calculation, the lower level polarization was neglected. The obtained results were compared with experimental results as well as theoretical results. It was found that the obtained results agree well with these results.
