论文摘要
在众多的激发能量上，对8BE核状态的严格理论研究进行了簇状态。这些状态的α聚类程度的数量：光谱因素，簇形式和α-末期宽度是在开发出准确的Ab Insibor方法的框架内计算的。 8BE频谱的其他基本特性：同时计算同胞素的结合和激发能，平均值。在大多数情况下，计算的结果与光谱数据达成了良好的一致性。做出了许多预测，并提出了相应的验证实验。已经证明了开发的核谱法的前景。
Scrupulous theoretical study of 8Be nucleus states, both clustered and non-clustered, is performed over a wide range of the excitation energies. The quantities which characterize the degree of the alpha-clustering of these states: spectroscopic factors, cluster form factors as well as the alpha-decay widths are computed in the framework of an accurate ab initio approach developed. Other basic properties of 8Be spectrum: the binding and excitation energies, mean values of the isospin are calculated simultaneously. In the majority of instances the results of the computations turn out to be in a good agreement with the spectroscopic data. A number of predictions are made and corresponding verification experiment is proposed. Prospects of the developed approach for nuclear spectroscopy are demonstrated.
