许多最奇特的中子 - 质子不对称核是在高能碎裂反应中以相对较少的数量产生的。它们作为每核子能量为100兆电子伏特或更高的快速次级束产生。对从这类次级束中利用和评估快速单核子及双核子移除反应所取得的进展以及近期的研究结果进行了综述。这包括将所使用的突然近似、程函反应模型与更多的从头算核结构输入相结合的最新研究工作。还概述了利用中子拾取反应来研究奇特核中类粒子态的潜在用途。
Many of the most exotic neutron-proton asymmetric nuclei are produced in relatively small numbers in high-energy fragmentation reactions. They are produced as fast secondary beams with energies of 100 MeV per nucleon or more. Developments made and recent results that both exploit and assess fast one- and two-nucleon removal reactions from such secondary beams are reviewed. This includes very recent work that interfaces the sudden, eikonal reaction models used with more ab-initio nuclear structure inputs. The potential use of neutron pick-up reactions to study particle-like states in exotic nuclei is also outlined.
