我们展示了使用共振相干激发快离子的选择性激发作为一种新的技术来研究护航电子的生产。结果表明，电子从激发态的损失起着重要的作用，护送电子的产生快通道离子。由类氢离子在{italn}=2状态的护航生产的绝对截面来自dtaa，作为离子能量的函数的共振相干激发的绝对概率的估计。
We demonstrate the use of selective excitation of fast ions by resonant coherent excitation as a new technique to study convoy electron production. It is shown that electron loss from excited states plays an important role in convoy electron production by fast-channeled ions. The absolute cross section for convoy production by hydrogenic ions in {ital n}=2 states is derived from the dtaa, as is an estimate of the absolute probability of resonant coherent excitation as a function of ion energy.
