高电荷态离子的相对论沟道实验提供了晶体中各种原子状态和过程的有价值的信息。周期性晶体势迫使离子轨迹远离原子弦/平面，并抑制电子丢失/捕获概率。它导致更小的能量损失，由于晶体场和共振相干激发（由周期性晶体场的原子级激发）的高电荷态重离子的磁阻依赖的斯塔克能级混合。报道了HIMAC的最新进展，重点是在高电荷态离子的电荷交换和能量损失中观察到的共振相干激发。
Relativistic channeling experiments of highly-charged ions provide valuable information of a variety of atomic states and processes in the unique environment of a crystal. A periodic crystal potential forces an ion trajectory away from an atomic string/plane and depresses electron loss/capture probabilities. It leads to smaller energy loss, trajectory-dependent Stark level mixing due to the crystal field and resonant coherent excitation (atomic level excitation by the periodic crystal field) of highly-charged heavy ions. Recent progress at HIMAC is reported with an emphasis of resonant coherent excitation observed in charge exchange and energy loss of the highly-charged ions.
