Deuteron induced reactions on Li targets are candidate reactions for the neutron source in the International Fusion Materials Irradiation Facility (IFMIF) program. However, the theoretical model calculation of the reaction cross sections underestimates the experimental data. The incomplete fusion process, in which a part of a projectile is absorbed by a target, may contribute significantly in the reaction, and the understanding of the reaction mechanism is required. Since a weakly bound nucleus, such as deuteron, breaks up easily in the reaction, the model taking into account the breakup process is required for the analysis. We extended the Continuum-Discretized Coupled-Channels (CDCC) method, and applied to the analysis of incomplete fusion reaction. In the present paper, we show results of incomplete fusion cross section in the deuteron induced reaction on Li target, and discuss the importance of the process.
