Abstract: The recent developments mainly in nuclear interaction and many-body techniques allow us to compute the properties of finite nuclei. The applicability of the ab initio calculations is expanding to the mass number ~ 100 [1]. However, it becomes difficult to find a reliable result for further heavy nuclei, primarily due to the memory expensive three-nucleon interaction. To overcome the limitation and make the computation of the heavier nuclei feasible, we proposed a new storage scheme of the 3N matrix elements [2]. This new scheme enables us to compute the heavier nuclei well beyond the previous limitation. In this talk, I will present our results and predictions for lead 208, the known heaviest doubly magic nucleus [3].
