Abstract

The cosmological ⁷Li problem has been one of the big issues left in the standard Big-Bang nucleosynthesis (BBN) model. In order to determine the radiogenic 7Li abundance by the BBN, it is important to know the production and the destruction rate of ⁷Be rather than ⁷Li itself. We performed indirect measurements of the relevant neutron-induced reactions ⁷Be(n, p)⁷Li and ⁷Be(n, α)4He simultaneously by the Trojan Horse Method (THM) via the three-body reactions ⁷Be(d,⁷Lip)¹H and ⁷Be(d, αα)¹H. A ⁷Be 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 ⁷Be(n, p₁)⁷Li^∗ contribution may be obtained by carrying out a further data analysis.
