Description
The study and measurements on stable nuclei have been extensively performed since the discovery of atomic nucleus in early 20th century. Their physics properties such as mass, life-time, saturation density property, radii, and their stability have been researched and the knowledge obtained in those studies made the basis of understanding about nuclear structures, strong interaction of nucleons in nuclei, and behaviour of nuclear matter.
In these a few tens of years, the study of nuclear physics is not limited on the stable or sub-stable nuclei but enhanced to the short-life unstable nuclei. The intense heavy ion beam provided by the current accelerator facilities enables us to artificially produce even the drip-line nuclei far from the stability line, and to learn the property of exotic nuclei experimentally with the help of advanced fragments separator and developed detector setups. The new isotopes, the location of the drip line, mass and life time of exotic nuclei are being challengingly explored and measured. Through the nuclear reaction measurements, many other properties, i.e. evolution of nuclear shell structure from the stability line to the drip line and neutron halo and skin structures are being systematically studied.
In this lecture, the current advanced radio active beam facilities and the method to produce short-life unstable beam will be introduced. The recent nuclear physics experiments on exotic nuclei in those facilities will be also introduced.
