models and its parameters. Further data analysis is in progress to make clear the dependency of fragment
production on energy, mass, and angle.
4. Conclusion
We measured systematic DDX data down to 0.5 MeV/u for proton-induced fragment-production
reactions on C, N, O, Al, Ti and Cu. The results were consistent with the other experimental results from
comparison of the Al(p,xLi) and Al(p,xBe) results for Ep=200 MeV. From the Al(p,x) data, the amounts of
B and C emission are comparable to Li and Be emission. From the C(p,xLi) data for various proton
energies, two body reaction process that indicated cluster structure of target nuclei was observed for lower
incident proton energy. Further data analysis is undergoing to derive not only systematic data set but also
pictures of fragment production reaction. The both results would help to improve treatment of fragment
production that is used for energy deposition calculation in a matter.
