The understanding of nucleon (N) and triton emissions from nucleon-Li7 collision is important for the development of some fusion-related facilities. Both nucleon and triton emissions from nucleon-induced reactions on Li7 leading to three final particles at incident energies below 20 MeV are analyzed by using a three-body continuum discretized coupled-channels method (CDCC), final-state interaction (FSI) model, and sequential decay (SD) model. The CDCC is applied to predict nucleon and triton emissions via breakup continuum channels, Li7(N,N′)Li∗7→t+α. Triton emission from the p(n) + Li7→t+Li5(He5) channel and nucleon emission from sequential decay of the ground-state Li5(He5) are described by the FSI model and the SD model, respectively. The double differential cross sections (DDXs) of nucleon and triton emissions are calculated and compared with experimental data. In most cases, the calculated DDXs are in good agreement with the measured ones except at relatively low nucleon emission energies. It is clarified that triton production takes place mainly via the breakup continuum channels.
