摘要：

Transfer and excitation, resulting from simultaneous electron capture and K-shell excitation in a single collision, has been measured 280-310-MeV Ti20+ ions channeled in the <100> axis of a thin Au single crystal. The 19+ charge-state fraction of the Ti ions exiting the Au crystal was measured as a function of ion energy and showed no narrow peak attributable to resonant transfer and excitation (RTE). The number of Ti K alpha x rays, emitted by the Ti ions due to RTE, in coincidence with Ti19+ was also measured at two energies, on and off the previously reported narrow resonance, and again no evidence for a narrow resonance was observed.
