Abstract
Lyman-alpha lines of hydrogenlike Ti21+ have been observed with an electron -beam ion trap. The intensity ratio between Lyman-alpha (1), and -alpha (2) was measured at electron energies of 10.6, 24.7, and 49.6 keV (2.12, 4.96, and 9.96 in threshold units). The linear polarization of Lyman-alpha (1) w as obtained by comparing the experimental intensity ratio at an observation angle of 90 degrees with the total emission cross section ratio calculated by a simple collisional radiative model. The present results are compared with existing theoretical results.
