Abstract

The registration of inelastically scattered particles (α or d) in coincidence with particles emitted during the decay of these states is proposed to determine the cluster structure of excited states of the ⁹Be nucleus. ⁹Be(α, α'x) and ⁹Be(d, d 'x) reactions are simulated kinematically. It is shown that analyzing the energy spectrum of a decay particle (e.g., x = n, α) allows the contribution from different cluster configurations to the structure of these states to be determined. An experimental setup is created and tested that allows detection of scattered alpha-particles in coincidence with a decay particle. Spectra of the scattered alpha particles in coincidence with neutrons and gamma quanta are obtained.

能量为30 MeV时9 Be（α，α'n）X重合的实验

摘要

提出了非弹性散射粒子（α或d）与这些态衰减过程中发射的粒子一致的配准，以确定⁹ Be核激发态的簇结构。⁹为（α，α ' X）和⁹成为（d，d  ' X）反应模拟运动学。结果表明，分析衰变粒子的能谱（例如，x = n，α）允许确定来自不同簇配置对这些状态的结构的贡献。创建并测试了一个实验装置，该装置可以检测与衰变粒子同时发生的散射α粒子。获得与中子和伽马量子一致的散射α粒子的光谱。
