5. Abstract: The US Nuclear Scientific Advisory Committee recently published the Long Range Plan for US

Nuclear Science and two important open questions were addressed: \Where do nuclei and elements

come from?" and \What combinations of neutrons and protons can form a bound atomic nucleus?"

Their answers are crucial for both nuclear structure and astrophysics, gaining our knowledge about

modern nuclear theory and the evolution of our Universe. Moreover, with the recent astonishing

observation of the first neutron star merger by astronomers, understanding nuclear spectroscopic

properties of unstable isotopes has become very important to demonstrate observables of such event

including gamma-ray, optical and X-ray emissions. However, our knowledge of short-lived nuclei

involved in nucleosynthesis processes, such as the rapid proton capture process (rp-process) and the

rapid neutron capture process (r-process), still lags behind the precision at which the observations

have been made. In order to answer the questions, new experimental studies of nuclear properties

with heavy ion radioactive beam accelerators are critical. Moreover, because most of key nuclei allow-

ing us to explore new models of nuclear structure are far from stability, it is only possible to perform

the research with powerful rare isotope beam (RIB) facilities, including National Superconducting

Cyclotron Laboratory, Oak Ridge National Laboratory, CARIBU at Argonne National Laboratory,

MARS at Texas A&M University Cyclotron Institute, which provide short-lived radioactive beams.

Furthermore, new generation RIB accelerator facilities around the world will be available soon, such

as Radioactive Isotope Beam Factory (RIBF) in Japan, Facility for Rare Isotope Beam (FRIB) in the

US and Rare isotope Accelerator complex for ON-line experiment (RAON) in South Korea. Recent

experimental studies of key nuclei performed at the existing facilities will be presented as well as

new active research activities at the Center for Exotic Nuclear Studies (CENS), Institute for Basic

Science (IBS). Future plans on how to take advantage of the new facilities including RAON will also

be addressed.
