| Abstract | An ion passing through a mono-crystalline target gfeelsh an oscillating electric field with frequencies determined by its velocity and the crystal indices. When the frequency fits the energy difference between the two levels of the ions, a so-called resonant coherent excitation (RCE) sets off. We have been intensively studying dynamic aspects of the RCE process with gmediumheavyh highly-charged ions ( Z = 18 or 26) of ∼400 MeV/u [1,2,3] at NIRS-HIMAC, Japan. Here we report on commissioning experiments for applying the 2D (two-dimensional)-RCE process to a high resolution spectroscopy of gheavyh highly-charged ions employing ion beams supplied from the SIS at GSI. We concentrated on a transition of 1s22s1/2-1s22p3/2 (the transition energy is 4459 eV) of 191.5 MeV/u Li-like U 89+ ions. A well collimated beam with small divergence passed through the (220) atomic plane of a 7 μm-thick Si crystal mounted on a goniometer. We tuned the resonance condition by rotating the crystal with respect to the beam direction, |
