Searching for effective pathways for the production of proton- and neutron-rich isotopes through an optimal combination of reaction mechanism and energy is one of the main driving forces behind experimental and theoretical nuclear reaction studies as well as for practical applications in nuclear transmutation of radioactive waste. We report on a study on incomplete fusion induced by deuteron, which contains one proton and one neutron with a weak binding energy and is easily broken up. This reaction study was achieved by measuring directly the cross sections for both proton and deuteron for Pd at 50 MeV/u via inverse kinematics technique. The results provide direct experimental evidence for the onset of a cross-section enhancement at high energy, indicating the potential of incomplete fusion induced by loosely-bound nuclei for creating proton-rich isotopes and nuclear transmutation of radioactive waste.

The fifth symposium on Science of Hadrons under Extreme Conditions, organized by the Research Group for Hadron Science, Advanced Science Research Center, was held at Tokai Research Establishment of JAERI on March 18 to 20, 2003. The symposium was devoted for discussions and presentations of research results in wide variety of hadron physics such as nuclear matter, hypernuclei, neutron stars, supernovae, nucleosynthesis, heavy-ion reactions, quark matter and quantum chromodynamics to understand various aspects of hadrons under extreme conditions. Thirty three papers on these topics presented at the symposium aroused lively discussions among approximately 50 participants. The concluding remark for the "research group for hadron science" and the explanation of next project "research group for manybody theory of hadron systems" was also presented by the group leader Dr. S. Chiba with gratitude to the participants and to all the scientists concerned.
