“…In a set of publications [3,4,5,6,7,8] the photodisintegration of 9 Be into two alpha-particles and a neutron has been considered within the orthogonality condition model (OCM) which make uses the Gaussian basis and the complex scaling method (CSM) to locate resonance states. In these papers the 1/2 + excited state was shown to be a virtual state situated a very close to the two-cluster 8 Be+n threshold.…”

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