摘要：

The article discusses nuclear ground state correlations (GSCs), which are particularly clearly manifested when using the formalism of quantum Green's functions (GFs) and Feynman diagrams. In addition to the one-particle-one-hole ground state correlations in the well-known random phase approximation (RPA) method, there also exist and make a noticeable quantitative contribution GSCs that arise from using more complex configurations than in RPA, specifically, configurations containing phonons and those containing only three quasiparticles, phonon-GSCs and GSC3s, respectively. The latter case of GSC3 is discussed in detail in this paper. It has been shown that GSC3s make a significant quantitative contribution to problems related to explaining certain characteristics of low-lying excited states (phonons) and transitions between them in even-even nuclei.
