在逆运动学中研究轻离子与奇异束的反应，可以获得远离稳定区的广泛核结构信息。目前正在达姆施塔特建造的未来FAIR设施将为研究奇异核提供新的机会。概述了EXL计划作为NUclear结构、天体物理和反应部分的物理计划。它被建议作为一个通用的高精度探测器设置周围的内部目标的存储环伴随着重离子标记环探测器和探测器的快速质子和中子。可能实现的设置进行了简要讨论。早期的可行性研究，稳定的存储光束和密集的研发，对探测器能够在超高真空条件下工作，帮助准备实验装置的最终设计。本文介绍了在实验储存环（ESR）中用稳定离子进行的散射实验和用放射性离子进行的第一反应实验的结果。还描述了EXL项目在ESR的原型设置和可能的更大规模设置的未来前景。
The investigation of light-ion induced reactions with exotic beams in inverse kinematics gives access to a broad range of nuclear structure information in the region far off stability. The future FAIR facility, currently under construction at Darmstadt, will provide new opportunities for studying exotic nuclei. The physics program of the EXL project planned as a part of NUclear STructure, Astrophysics and Reactions at FAIR is outlined. It is proposed as a universal high-precision detector setup surrounding the internal target of the storage ring accompanied by a heavy-ion tagging ring detector and a detector for fast protons and neutrons. Possible realization of the setup is briefly discussed. Earlier feasibility studies with stable stored beams and intensive R&D towards the detectors capable of working in ultra-high vacuum conditions helped preparing the final design of the experimental setup. Results of scattering experiments with the stable ions and a very first reaction experiment performed with radioactive ions in the experimental storage ring (ESR) are presented. Future perspectives of the EXL project with a prototype-setup at the ESR and a possible larger-scale setup are also described.
