We study the nature of the low-lying resonance states in mirror nuclei 9 Be and 9 B. Investigations are performed within a three-cluster model. The model makes use of the hyperspherical harmonics, which provides a convenient description of the three-cluster continuum. The dominant three-cluster configurations α + α + n and α + α + p in 9 Be and 9 B, respectively, are taken into account. Dominant decay channels for all resonance states in 9 Be and 9 B are explored. Much attention is paid to the controversial 1/2 + resonance states in both nuclei. We study effects of the Coulomb interaction on the energy and width of three-cluster resonances in the mirror nuclei 9 Be and 9 B. We also search for the Hoyle-analog state, which is a key step for alternative ways to synthesize 9 Be and 9 B in triple collisions of clusters in a stellar environment.

Elastic longitudinal electron scattering form factors have been studied for 9 Bein the frame work of 1p-shell model, which considered as the core of 4 He With five neucleons disturbuted out of the core. The basis of no-core shell model space with ω h ) 2 0 ( + truncations are used also to study the effects of effective charge on the elastic longitudinal form factors. A good agreement of results are obtaining with the experimental data for both models considered in this work. The reduced transition probabilities B(C2) calculated for the two kinds of model space and for the effective charges which are used in this work.

Abstract. The photodisintegration cross section of the 9 Be(1/2 + ) state is investigated in a framework of the α + α + n three-body model. The 1/2 + state of 9 Be locates just above the three-body threshold, and the s-wave neutron property of this state is a long-standing problem. It has been a topic of quite interest in relation to the breakup mechanism of 9 Be into the 8 Be(0 + ) + n and (α + α + n) channels.
