Abstract
Relative intensities and polarization rates of heliumlike Lyman x rays emitted in collisions of 4-keV/amu ions with have been measured. Our experimental results are discussed in connection with molecular calculations for the near-system +H. High polarization rates (∼60%) are measured for direct x rays, indicating a strong predominance of substates in final states, in agreement with the theory. This shows the existence of a strong rotational coupling in the molecular frame. The difference of polarization observed for the and x rays may originate from a higher anisotropy of the low-angular-momentum states with respect to the high ones, as predicted by the theory.
