Experimental study of mirror nuclei ¹⁰Be-¹⁰C, ¹¹B-¹¹C, and ⁹Be-⁹B populated via ¹⁰B+¹⁰B nuclear reactions

NUCLEAR REACTIONS ¹⁰B(¹⁰B, ¹⁰B), (¹⁰B, ¹⁰B'), (¹⁰B, X)¹¹C/⁹Be/⁹B, E=50, 72.2 MeV; measured reaction products. ⁹Be, ^9,10B, ¹¹C; deduced excitation spectrum, mirror analog states, states in compact shell-model configurations (e.g., members of ground-state rotational bands) show very small mirror energy differences (consistent with standard Coulomb displacement energies), whereas spatially extended clusterlike states exhibit significantly reduced energy gaps consistent with the Thomas-Ehrman shift, level energies, J, π.
