Title: 从头计算重整化随机相位近似框架中的核物质和光谱核性质

Abstract: A modern chiral potential incorporating the three-body force is adopted to investigate bulk properties, spectra, and nuclear responses of closed-(sub)shell nuclei throughout the nuclear chart within a particle-hole (p-h) renormalized random-phase approximation (RRPA) scheme using a Hartree- Fock (HF) single-particle basis. Our analysis shows that all instabilities induced by the quasiboson approximation (QBA) underlying RPA are removed and an overall better consistency with the experiments is achieved for all observables of the investigated nuclei. The residual discrepancies point out the need of going beyond the p-h space. Show Chinese abstract

Abstract: 现代手性势结合三体力被采用，以研究整个核图中闭-(次)壳核的体积性质、能谱和核响应，在使用哈特里-福克（HF）单粒子基的粒子-空穴（p-h）重整化随机相位近似（RRPA）方案中。 我们的分析表明，由RPA基础的准玻色子近似（QBA）引起的所有不稳定性都被消除，并且对于所研究核的所有可观测量，与实验的整体一致性得到了改善。 残留的差异指出了超越粒子-空穴空间的必要性。
