Systematic analysis of $t$ and $^3$He breakup reactions
Abstract
Systematic measurement of and He 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 and He 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 and He reactions. The breakup cross section of is found to be almost the same as that of He and is about one-third of that of . Coulomb breakup plays negligible role in the breakup of and He, in contrast to in the deuteron breakup reaction. It is found that and He tend to breakup into three nucleons rather than and a nucleon. It is shown that the breakup cross sections of and He 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 and He.
