Underground experimental study finds no evidence of low-energy resonance in the ⁶Li(p, γ)⁷Be reaction

NUCLEAR REACTIONS ⁶Li(p, γ)⁷Be, (p, α)³He, E=80-400 keV; measured Eγ, Iγ, Eα, Iα, ³He using an HPGe detector for γ rays and a Si detector for particles at the Gran Sasso Laboratory for Underground Nuclear Astrophysics (LUNA); deduced σ(E), astrophysical S(E) factors, and astrophysical reaction rates for the ⁷Li(p, γ) reaction, no evidence for a reported resonance at 195 keV, corresponding to a positive-parity state in ⁷Be. Comparison with previous experimental results, and NACRE data. R-matrix fit of the present and earlier experimental data.
