Spectral lines for polarization measurements of the coronal magnetic field. III. Atomic data for SiIX
Författare
Summary, in English
We report on large-scale ab initio multiconfiguration Dirac-Fock (MCDF) calculations for spectral lines of Si IX, with emphasis on the forbidden transitions 2p(2) P-3(J-->J'). The J = 0 --> J' = 1 transition at 3.9346 mu m holds promise as a diagnostic of coronal magnetic fields if and when future coronagraphic instruments can measure the polarized light at this wavelength.
