On three-cluster disintegration of 9Be

Abstract

We study a process of the photodisintegration of some Borromean light nuclei into three clusters. Thisstudy is performed within a three-cluster microscopic model. In Reference [1] this model was applied toobtain parameters of resonance states in 9Be and 9B and to establish their nature. Main aim of the presentinvestigations is to describe the dipole transition probability from the ground state of 9Be to the states ofthree-cluster α+α+n continuum by using the same model. That model exploits the hypersphericalharmonics basis (HHB) and thus reduces many-channel Schrodinger equation to the algebraic matrix(AM) form. The dipole transitions from the ground 3/2- state to the 1/2+ states of three-cluster continuumwere studied in detail. The role of resonance states in three-cluster continuum to this process isinvestigated in detail. The dominant channels with the maximal dipole strength due to the couplingbetween the ground and scattering states are discovered
