将光谱学的领域扩展到非常富含中子的重核，受到了反应[ital Q]值的影响，这些值一直有利于形成较轻的同位素。放射性光束提供了克服这一困难的机会。我们进行了系统的研究，以确定实际的中子过剩的弹丸，需要恢复上述趋势的多核子转移过程的截面。这种识别，辅以定量预测的生产产量，提供了具体的指导方针选择的反应伙伴和轰击条件。
Extending the field of spectroscopy to very neutron-rich heavy nuclei has been impaired by reaction [ital Q] values that consistently favor the formation of the lighter isotopes. Radioactive beams offer a chance to overcome this difficulty. We carry out a systematic study of cross sections for multinucleon transfer processes in order to determine the actual neutron excess in the projectiles that is needed to revert the aforementioned tendency. This identification, supplemented by quantitative predictions for the production yields, provide concrete guidelines for the selection of reaction partners and bombarding conditions.
