摘      要：Scrupulous theoretical study of 8Be nucleus states,both clustered and non-clustered,is performed over a wide range of excitation *** quantities that characterize the degree of the alpha-clustering of these states,i.e.,spectroscopic factors,cluster form factors,and alpha-decay widths,are computed in the framework of the developed accurate ab initio *** basic properties of the 8Be spectrum,including the binding and excitation energies and the mean values of the isospin,are calculated *** the majority of instances,the results of the computation turn out to be in good agreement with the spectroscopic data.A number of predictions are made,and corresponding verification experiments are *** of the developed approach for nuclear spectroscopy are demonstrated.
