本文利用已发表的Be和B同位素的转移反应数据，讨论了基于α-α势的核二聚体的结构及其转动带，并讨论了4价核的共价价中子。基于12 C中的0+2态，假定它是一个3 α粒子链，激发能为7.65MeV，并加入共价核子，构造了12 C * +x中子系统的链态.估算了最低链态的能量位置，并提出了在9 Be和放射性束反应中布居的途径。预计这些状态是亚稳态的，并且可能具有可观的γ衰变分支。外推到较长的链状态，聚合物，在富含中子的轻同位素。
SummaryThe structure of nuclear dimers and their rotational bands based on the α-α potential and covalent valence neutrons with up to 4 valence nucleons are discussed using published transfer reaction data for Be and boron isotopes. Based on the 0+2 state in12C, which is assumed to be an 3 α-particle chain at an excitation energy of 7.65 MeV and adding the covalent nucleons, chain states in the system12C* +x neutrons are constructed. The energy position of the lowest chain states are estimated and ways for their population in reactions on9Be and using radioactive beams are proposed. It is expected that these states are metastable and could have appreciable branches for γ-decay. Extrapolations to longer chain states, polymers, in neutron-rich light isotopes are made.
