摘要：

We measured the emerging charge-state distribution of hydrogen-like 390 MeV/u Ar17+ ions planar channeled in a silicon surface barrier detector for the DeltaE measurement, and observed their energy deposition in the detector simultaneously. We simulated the energy loss spectrum of specific emerging charge state, and succeeded in reproducing it with an adjusting parameter for the cut-off momentum transfer between close and distant collisions.
