The linear polarization of the 1s2p 1P1-->1s2 1S0 resonance line, the 1s2p 3P1,2-->1s2 1S0 intercombination lines, and the 1s2s 3S1-->1s2 1S0 forbidden line was measured in heliumlike Fe XXV excited near threshold by a monoenergetic electron beam. The measurement was carried out with a high-resolution x-ray spectrometer employing a set of two analyzing crystals that acted as polarizers by selectively reflecting the individual polarization components. A value of +0.56+0.17-0.08 was determined for the polarization of the 1P1 line, -0.53+0.05-0.02 for the 3P2 line, -0.22+0.05-0.02 for the 3P1 line, and -0.076+0.007-0.007 for the 3S1 line. The measurements were compared with results from a relativistic distorted-wave calculation, which was carried out for a number of mid-Z heliumlike ions (Mg10+-Kr34+), and good agreement was found. By contrast, disagreement was noted with predictions based on Coulomb-Born calculations, allowing us to distinguish between theoretical approaches.
