Abstract

The first results on analysis of determination of the contribution of decays of unstable 8Be and 9B nuclei and the Hoyle 3α-state into the dissociation of 14N → 3He (+H) are presented. Layers of nuclear track emulsion longitudinally exposed to 2.9 A GeV/с 14N nuclei at the JINR Nuclotron are used as the research material. Under the assumption that He and H fragments preserve momentum per nucleon of the primary nucleus, these unstable states are identified by the minimum invariant mass calculated using fragment emission angles.

在 14N 核解离中搜索 9B 核和霍伊尔状态的衰变

摘要

介绍了确定不稳定8 Be 和9 B 核的衰变以及霍伊尔 3α 态对14 N → 3He (+H)解离的贡献的分析的第一个结果。将在 JINR Nuclotron处纵向暴露于 2.9 A GeV/ ? 14 N 原子核的核轨道乳液层用作研究材料。假设 He 和 H 碎片保持初级核的每个核子的动量,这些不稳定状态由使用碎片发射角计算的最小不变质量来识别。
