Systematic measurement of t and 3He knockout processes is planned. The weakly-bound nature of these nuclei may affect the interpretation of forthcoming knockout reaction data. Purpose: We aim at clarifying breakup properties of t and 3He by investigating their elastic and breakup cross sections. We employ the four-body continuum-discretized coupled-channels method with the eikonal approximation to describe the t and 3He reactions. The breakup cross section of t is found to be almost the same as that of 3He and is about one-third of that of d. Coulomb breakup plays negligible role in the breakup of t and 3He, in contrast to in the deuteron breakup reaction. It is found that t and 3He tend to breakup into three nucleons rather than d and a nucleon. It is shown that the breakup cross sections of t and 3He are not as large as those of d but non-negligible. Because about 80% of them corresponds to the three-nucleon breakup process, a four-body breakup reaction model is necessary to quantitatively describe the breakup of t and 3He.
