论文摘要
提出了分析的第一个结果,以确定不稳定的$^{8} $ be和$^{9} $ b nuclei和hoyle 3 $α$ - 州对$^{14} $ n $ \至$ 3HE(+H)分离的衰减的贡献。作为研究材料,在Jinr nuclotron上与核轨道乳液的层纵向暴露于2.9 $ a $ a $ gev/$ c $^{14} $ n nuclei。在假设HE和H片段保留了原核的每个核子的动量,这些不稳定状态是通过从片段的发射角度计算得出的不变质量来识别的。
First results of an analysis to determine contribution of decays of the unstable $^{8}$Be and $^{9}$B nuclei and the Hoyle 3$α$-state to dissociation of $^{14}$N $\to$ 3He (+H) are presented. As the research material, layers of nuclear track emulsion longitudinally exposed to 2.9 $A$ GeV/$c$ $^{14}$N nuclei with at the JINR Nuclotron. Under the assumption that the He and H fragments retain momentum per nucleon of the primary nucleus, these unstable states are identified by the invariant mass calculated from the emission angles of the fragments.
