INVESTIGATION OF THE PARTIAL CHANNEL OF 8Be NUCLEUS GROUND STATE FORMATION IN THE 14N(γ,2α6Li) REACTION

Abstract

Using the track 4𝜋-detector method (a diffusion chamber arranged in a magnetic field on the way of a beam of bremsstrahlung photons with the final energy 𝐸𝛾max = 150 MeV), the reaction 14N(γ,2α6Li) has been studied. The distributions of events over the excitation energy of 2𝛼-particles were analyzed and a channel of the formation of the 8Be nucleus in the ground state was revealed and has been separated. Events in which the 𝛼-particle pairs correspond to the formation of the 8Be nucleus in the ground state can be reliably identified. The energy and angular distributions of 𝛼 particles at each stage of decay are analyzed.
