Abstract
The Coulomb shift is analyzed for the mirror cluster systems of and by applying the orthogonality condition model (OCM). The OCM calculation clearly predicts the suppressed excitation energy of the higher states in the proton-rich system of . This results can be interpreted in terms of the extension of the Thomas-Ehrman shift (TES), which is discussed in and , to the cluster degrees of freedom. A combination of the cluster TES and the monopole transition is proposed as an experimental probe to identify the cluster structure in mirror systems.
