Аннотация

Anisotropic distributions of the Lyman-α1 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 2p3/2 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 mj=±1/2 magnetic substates is about two times more probable than to the mj=±3/2 ones.
