从实际核子-核子力计算^{16}O,^{40}Ca和^{56}Ni周围原子核的基态和单粒子能量

摘要:

我们使用真实的核子-核子力对^{16}O、^{40}Ca和^{56}Ni周围的原子核进行了从头计算。特别地,^{56}Ni在这种从头计算中被计算为最重的核。在幺正模型算符方法的框架内得到了包含三体团簇效应的基态和单粒子能量。结果表明,对于所有核,CD-Bonn核子-核子势都给出了接近实验值的很好结果。

英文摘要:

We perform ab initio calculations for nuclei around ^{16}O, ^{40}Ca, and ^{56}Ni using realistic nucleon-nucleon forces. In particular, ^{56}Ni is computed as the heaviest nucleus in this kind of ab initio calculation. Ground-state and single-particle energies including three-body-cluster effects are obtained within the framework of the unitary-model-operator approach. It is shown that the CD-Bonn nucleon-nucleon potential gives quite good results close to the experimental values for all nuclei in the present work.
