Measurement of the ⁷Li(γ, t)⁴He ground-state cross section between E_γ = 4.4. and 10 MeV

NUCLEAR REACTIONS ⁷Li(γ, t), E=4.4-10 MeV from High Intensity Gamma-ray Source (HIγS) at TUNL; measured E(t), I(t), Eα, Iα, Eγ and Iγ, αt-coin, ground state σ(E) using the SIDAR silicon detector array. ³H(α, γ), E(cm)=0-7 MeV; deduced astrophysical S-factor from R-matrix analysis. Comparison with model predictions, and with previous experimental results. Relevance to primordial Li problem and the mirror α-capture reactions.
