A γ-ray spectroscopic study of
10 B is reported. Excited states in10 B were populated in inelastic proton scattering and their γ-decays were measured with the ELIFANT array, a state-of-the-art spectrometer with large volume LaBr3 :Ce and CeBr3 detectors placed in anti-Compton shields and having unprecedented efficiency for high-energy γ rays. A few weak transitions were observed in the experiment, namely M3 transition between Jπ , T = 0+ 1 , 1 isobaric analog state to the Jπ , T = 3+ 1 ,0 ground state and E2 transition between the Jπ , T = 2+ 1 ,0 state and the isobaric analog state. The results are compared to a new set of ab initio no-core shell model calculation using the newest version of the local position-space chiral N3 LO nucleon-nucleon interaction, which correctly reproduces the spectrum of the excited states in10 B, a problem of the theory in previous years.
