Description

Nucleon-nucleon (NN) interaction is one of the strongest pillars of the nuclear many-body models. It plays a key role in interpreting experimental findings and unfolding new properties of nuclei which add a new dimension in our understanding of nuclei. In the seminar, I’ll discuss the physics of nuclei that my group and I have observed based on the properties of NN interaction. The evolution of nuclear shell structure in exotic nuclei has been one of the fascinating observations in the last two decades.  I’ll discuss the role of nucleon-nucleon interaction in the evolution of shell structure for Sc, F, and Li isotopes. Furthermore, I’ll demonstrate the correlations between single-particle energy gaps and single-particle strength for building the level structure of Sc, F, and Li isotopes. With moving forward in the seminar, I’ll show that the shell model effective interaction in spite of having good prediction power may lack basic features for its components. We found such a problem in the tensor force of pf‒ and p‒ shell model interactions and presented a robust solution for it. In the end of the seminar, I’ll discuss about pseudo-mirror nuclei. These nuclei exhibit mirror symmetry in energy spectra like conventional mirror nuclei, and they are described by reasonably estimating the average of the overall strength of nucleon-nucleon force in terms of NpNn product, where Np and Nn is particle and hole number of protons and neutrons counted from nearest shell closures.
