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.

The neutrino driven wind model at core collapse supernovae is one of proposed scenarios explaining the origin of the element synthesis through the rapid neutron capture. My talk report the systematic direct measurements of the 
Li(
,n)
B reaction and so on, in order to clear the seed to neutron ratio, which is an important parameter to explain the heavy elemental abundance pattern. Based on the measurements, I indicate the dominant reaction flow as a function of the temperature at the stage of the alpha process, which is a prior process to the rapid neutron capture.
