Abstract

The registration of inelastically scattered particles (α or d) in coincidence with particles emitted during the decay of these states is proposed to determine the cluster structure of excited states of the 9Be nucleus. 9Be(α, α'x) and 9Be(d, d 'x) reactions are simulated kinematically. It is shown that analyzing the energy spectrum of a decay particle (e.g., x = n, α) allows the contribution from different cluster configurations to the structure of these states to be determined. An experimental setup is created and tested that allows detection of scattered alpha-particles in coincidence with a decay particle. Spectra of the scattered alpha particles in coincidence with neutrons and gamma quanta are obtained.
