Abstract

The applicability of Coulomb dissociation reactions to determine the cross section for the inverse neutron capture reaction was explored using the reaction 8Li(γ,n)7Li. A 69.5 MeV/nucleon 8Li beam was incident on a Pb target, and the outgoing neutron and 7Li nucleus were measured in coincidence. The deduced (n,γ) excitation function is consistent with data for the direct capture reaction 7Li(n,γ) 8Li and with low-energy effective field theory calculations.
