We study the nucleus, which accounts for most of the mass of the known universe. The nucleus is made of protons and neutrons and these protons and neutrons are in turn made of quarks and gluons. To understand this kind of hierarchical structure, we investigate the internal mechanism of quarks and gluons and then probe how the nuclei are formed out of protons and neutrons. Especially, we try to observer various new phenomena manifested in unstable, rare isotopes which draw worldwide attention these days. Based on these results, we also try to unravel the origin of the elements in this universe, when, where and how they are formed in the history of the universe.
