Elucidation of Shell Structure in Unstable Nuclei Based on Microscopic Nucleon-Nucleon Interactions

我们在微观核子-核子相互作用的基础上发展了新的有效相互作用。在证实了钙同位素中的能级反转可以通过利用这些相互作用的自洽平均场计算定量再现之后，我们研究了中质量到超重核的宽质量范围内的球形核的壳结构，并发现了一些可能出现不稳定核特有的新幻数的情况。我们还研究了库仑效应对核对、低能激发的性质以及从球形核到变形核的转变。

We have developed new effective interactions based on the microscopic nucleon-nucleon interaction. After confirming that the level inversion in the calcium isotopes is quantitatively reproduced by the self-consistent mean-field calculations using these interactions, we have investigated shell structure of spherical nuclei in wide mass range from medium-mass to super-heavy nuclei, and have found several cases in which new magic numbers specific to unstable nuclei may emerge. We have also investigated Coulombic effects on the nuclear pairing, properties of low-energy excitations, and transition from spherical to deformed nuclei.
