For the radiation protection of heavy ion accelerators, the pro-duction of secondary neutrons due to ion beam loss are fundamentalto estimate source terms. Alth
The work of last year was continued. LiF chips were exposed to 75MeV/u 12C and 25MeV/u 84Kr ion beamsat HIRFL, respectively. According to the results of last ye
The instable performance e.g. the neutron distribution information in neutron rich exotic nuclei is always aninterested subject. Some experiment results were ob
