摘要：

Anisotropic distributions of the Lyman-alpha(1) transition of the down-charged Xe53+ ions are observed in fast Xe54+ with Kr and Xe collisions, in which the electron is transferred by the nonradiative electron capture mechanism. At the energy of 95 MeV/u, the alignment parameter of the projectile 2p(3/2) state, A20, is determined to be -0.35 +/- 0.02 for both targets. While the projectile energy is 146 MeV/u, the parameter for the Kr and Xe target is -0.28 +/- 0.02 and -0.29 +/- 0.04, respectively. The present results demonstrate that the electron capture to the m(j) = +/- 1/2 magnetic substates is about two times more probable than to the m(j) = +/- 3/2 ones.
