This workshop will be held to discuss how to collaborate between Japanese and American scientists especially in the field of exotic nuclei. The present talk will be focused on a collaboration already in progress between JAEA, University of Tokyo, and Michigan State University (MSU) about the shell-model research for unstable nuclei. The Japanese group has developed a new scheme to construct a good effective interaction for the shell model calculation. To verify the validity of the scheme, experimental information for a new region is essential. Hence, we are collaborating with NSCL in MSU especially to investigate the single-particle property of exotic nuclei, leading to better understanding for the region of light exotic nuclei such as N=28 and heavier pf shell. On behalf of the collaboration, I will report the recent progress on this topics.
