Abstract
The lowest-lying states of the Borromean nucleus and its mirror nucleus are compared by using the hyperspheric adiabatic expansion. Three-body resonances are computed by use of the complex scaling method. The measured size of and the low-lying resonances of are first used as constraints to determine both central and spin-dependent two-body interactions. The interaction obtained reproduces relatively accurately both experimental three-body spectra. The Thomas-Ehrman shifts, involving excitation energy differences, are computed and found to be less than of the total Coulomb energy shift for all states.
