轻核Hoyle类态的系统研究

Systematic investigation of the Hoyle-analog states in light nuclei

V. S. Vasilevsky, K. Katō, N. Takibayev

摘要:

本文研究了轻核$^{9}$ Be、$^{9}$ B、$^{10}$ B、$^{11}$ B和$^{11}$ C的三集团连续谱共振态。这些原子核被认为具有由两个α粒子和中子、质子、氘核、triton和原子核$^{3}$ He组成的三簇结构。在这项研究中,我们使用两个不同的微观三集群模型。第一个模型采用超球谐函数基来计算通道和描述三簇连续体。第二种模型是著名的复尺度方法。核子-核子相互作用用半现实的Minnesota势和Hasegawa-Nagata势模拟。我们的主要目标是找到这些核中的Hoyle类似态,或者换句话说,是否有可能在团簇的三重碰撞中合成这些核。我们制定的标准,选择这样的国家和应用它们的共振态,出现从我们的计算。我们发现在恒星环境中,存在着符合所提出的判据的共振态,这使得这些核的合成成为可能。

英文摘要:

We investigate resonance states in three-cluster continuum of some light nuclei $^{9}$Be, $^{9}$B, $^{10}$B, $^{11}$B and $^{11}$C. These nuclei are considered to have a three-cluster configuration consisting of two alpha-particles and neutron, proton, deuteron, triton and nucleus $^{3}$He. In this study, we make use two different microscopic three-cluster models. The first model employs the Hyperspherical Harmonics basis to numerate channels and describe three-cluster continuum. The second model is the well-known complex scaling method. The nucleon-nucleon interaction is modeled by the semi-realistic Minnesota and Hasegawa-Nagata potentials. Our main aim is to find the Hoyle-analog states in these nuclei or, in other words, whether it is possible to synthesize these nuclei in a triple collision of clusters. We formulate the criteria for selecting such states and apply them to resonance states, emerged from our calculations. We found that there are resonance states obeying the formulated criteria which make possible syntheses of these nuclei in a stellar environment.
