Electron-ion recombination at magnetic storage rings is a well established field of research. Nevertheless, magnetic storage rings have the inherent limitation, that only ions with comparatively low mass-to-charge ratios can be stored for sufficiently long times such that meaningful recombination experiments can be carried out. The situation is fundamentally different at electrostatic storage rings which are capable of storing ions independent of their mass. Here, it is proposed to make use of this capability for novel electron-ion recombination studies with atomic ions (Fe+, Xe+) and with fullerene (C60) ions at the electrostatic cryogenic storage ring CSR of the Heidelberg Max-Planck-Institute for Nuclear Physics. In particular, we will investigate in how far electron-ion recombination of many electron-systems proceeds via collective excitations of bound electrons.

磁储存环上的电子-离子复合是一个公认的研究领域。然而，磁性存储环具有固有的局限性，即只有质荷比相对较低的离子才能存储足够长的时间，从而可以进行有意义的复合实验。这种情况在静电储存环中是根本不同的，静电储存环能够独立于其质量储存离子。在这里，它建议利用这种能力的新的电子-离子复合研究与原子离子（Fe+，Fe+）和富勒烯（C60）离子在静电低温储存环CSR的海德堡马克斯-普朗克核物理研究所。特别是，我们将调查在多远的电子-离子复合的许多电子系统的收益通过集体激发的束缚电子。
