Abstract Nuclear-structure studies with reaccelerated radioactive ion beams at the ISOLDE facility, CERN commenced with the REX-ISOLDE facility and continued after a major upgrade of the facility with the HIE-ISOLDE post-accelerator. The experiments are based on in-beam high-resolution γ -ray spectroscopy with Miniball, a spectrometer which comprises 24 six-fold segmented, encapsulated high-purity germanium crystals. The Miniball array has been used in Coulomb excitation and transfer-reaction experiments with exotic ion beams of energies up to 10 MeV/u. The investigations cover a wide range of nuclear structure topics which are addressed with beams ranging from beryllium up to heavy radium isotopes. Experimental conditions improved substantially after commissioning of the HIE-ISOLDE project at CERN with higher secondary-beam intensity, higher beam energy and better beam quality. We review the spectroscopy achievements obtained at REX-ISOLDE and first published results from HIE-ISOLDE.

在 REX-和 HIE-ISOLDE 处使用重新加速光束进行核结构研究

摘要 CERN 在 ISOLDE 设施使用再加速放射性离子束进行核结构研究，从 REX-ISOLDE 设施开始，并在使用 HIE-ISOLDE 后加速器对该设施进行重大升级后继续进行。实验基于使用 Miniball 的光束内高分辨率 γ 射线光谱学，Miniball 是一种光谱仪，由 24 个六倍分段、封装的高纯度锗晶体组成。Miniball 阵列已用于能量高达 10 MeV/u 的奇异离子束的库仑激发和转移反应实验。调查涵盖范围广泛的核结构主题，这些主题涉及从铍到重镭同位素的射束。在欧洲核子研究中心的 HIE-ISOLDE 项目投入使用后，实验条件得到了显着改善，二次光束强度更高，更高的光束能量和更好的光束质量。我们回顾了在 REX-ISOLDE 获得的光谱学成就和 HIE-ISOLDE 首次发表的结果。
