DETERMINATION OF EXCITATION ENERGY SPECTRUM OF Li IN THE n + Li REACTION

An experiment on the study of the He + t cluster structure of the Li nucleus in the reaction Li(n; He n)t was carried out on the RADEX neutron channel of the INR RAS at a neutron energy of 40–60 MeV. The excitation energy spectrum of Li was obtained in the range E = 16–50 MeV. At the excitation energy E = 16.6 MeV a resonance with Γ = 0.7 MeV was detected, and in the range E = 30–50 MeV two broad resonances E = 35.9 MeV with Γ = 8.4 MeV and E = 43.1 MeV with Γ = 5.4 MeV were detected. All levels are observed for the first time.
