Abstract
The dielectronic satellite radiation emitted from ions excited by resonant capture of an electron from a directed electron beam can be strongly linearly polarized. We have carried out relativistic calculations of angular asymmetry parameters and polarization of dielectronic satellite lines for H-like ions with Z=9, 22, 28, 42, and 92 using the multiconfiguration Dirac-Fock model. We found that many transitions exhibit strong angular asymmetry and a large degree of polarization. In addition, we found that the polarization of the resulting radiation is independent of atomic number in the nonrelativistic limit. But when the effects of relativity are taken into account, the polarization becomes markedly Z dependent.
