Resonance excitation in ⁷Be + d reaction to study the cosmological lithium problem

The objective of the present work is to study the unresolved ⁷Li abundance anomaly by carrying out experiments that destroy the rare isotope ⁷Be, the main source of ⁷Li. In our upcoming experiment (IS 554) at CERN-HIE-ISOLDE, using a 35 MeV ⁷Be beam, we plan to measure the (d,p) reaction with the silicon detector array T-REX. The higher beam energy, for the first time, would allow us to measure higher excitation energies in ⁸Be and a wider angular coverage would help in improved cross-section measurements without assuming isotropy done in earlier works
