In this paper we describe polarization spectroscopy measurements of O5+(1s(
2)3p(2)P(3/2)), following single-electron capture from He and H-2. A novel
arrangement for measurements of the polarization degree has been developed
to reduce the systematic error. These measurements are shown as a function
of projectile velocity, which was varied from 0.34 to 0.55 au. A simple mod
el for the results with H-2 is presented by considering the velocity depend
ence of capture cross sections for each 4l state and the cascade from 4l to
3p. However, for the case of the He target, no such simple model is found
to be consistent with the experimental results.
