本文研究了离子碰撞氖和氩二聚体（Ne ~（2 $）和Ar ~（2 $））引起的原子间库仑衰变对低能电子产生的贡献。我们的实验涵盖了广泛的扰动强度和反应通道。我们用11.37 MeV/u S$^{14+}$、0.125 MeV/u He$^{1+}$、0.1625 MeV/u He$^{1+}$和0.150 MeV/u He$^{2+}$作为射弹，研究了电离、单电子和双电子向射弹的转移以及射弹电子损失过程。COLTRIMS反应显微镜的应用，使我们能够恢复的三维动量矢量的离子对的碎片二聚体为Ne$^{q+}$/Ne$^{1+}$和Ar$^{q+}$/Ar$^{1+}$（q = 1，2，3），符合至少一个发射的电子。
We investigate the contribution of Interatomic Coulombic Decay induced by ion impact in neon and argon dimers (Ne$_2$ and Ar$_2$) to the production of low energy electrons. Our experiments cover a broad range of perturbation strengths and reaction channels. We use 11.37 MeV/u S$^{14+}$, 0.125 MeV/u He$^{1+}$, 0.1625 MeV/u He$^{1+}$ and 0.150 MeV/u He$^{2+}$ as projectiles and study ionization, single and double electron transfer to the projectile as well as projectile electron loss processes. The application of a COLTRIMS reaction microscope enables us to retrieve the three-dimensional momentum vectors of the ion pairs of the fragmenting dimer into Ne$^{q+}$/Ne$^{1+}$ and Ar$^{q+}$/Ar$^{1+}$ (q = 1, 2, 3) in coincidence with at least one emitted electron.
