Abstract
We study the nature of the low-lying resonance states in mirror nuclei and . 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 and in and , respectively, are taken into account. Dominant decay channels for all resonance states in and are explored. Much attention is paid to the controversial 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 and . We also search for the Hoyle-analog state, which is a key step for alternative ways to synthesize and in triple collisions of clusters in a stellar environment.
