摘要：

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 model for the results with H-2 is presented by considering the velocity dependence 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.
