| 英文摘要 | The cosmological Li-7 problem has been one of the big issues left in the standard Big-Bang nucleosynthesis (BBN) model. In order to determine the radiogenic Li-7 abundance by the BBN, it is important to know the production and the destruction rate of Be-7 rather than Li-7 itself. We performed indirect measurements of the relevant neutron-induced reactions Be-7(n, p)Li-7 and Be-7(n, alpha)He-4 simultaneously by the Trojan Horse Method (THM) via the three-body reactions Be-7(d, (7)Lip)H-1 and Be-7(d, alpha alpha)H-1. A Be-7 radioactive-isotope (RI) beam at 3.16 MeV/u was produced at Center-for-Nuclear-Study RI Beam (CRIB) separator. The Q-value spectra shows the evidence of the three-body channels of interest. We confirmed that the THM was applicable to the present measurements by the momentum distributions of the spectator proton. Preliminary excitation functions are roughly consistent with the previous studies, moreover providing new data in the BBN energy range, and suggesting that new information about the Be-7(n, p(1))Li-7* contribution may be obtained by carrying out a further data analysis. |
