Abstract

The structure of the F 24 nucleus has been studied at GANIL using the β decay of O 24 and the in-beam γ -ray spectroscopy from the fragmentation of Na 27, 28, Ne, 25, 26 and Mg 29, 30 nuclei. Combining these complementary experimental techniques, the level scheme of F 24 has been constructed up to 3.6 MeV by means of particle- γ and particle- γ γ coincidence relations. Experimental results are compared to shell-model calculations using the standard USDA and USDB interactions as well as ab initio valence-space Hamiltonians calculated from the in-medium similarity renormalization group based on chiral two- and three-nucleon forces. Both methods reproduce the measured level spacings well, and this close agreement allows unidentified spins and parities to be consistently assigned.
