Nuclear structure studies of 24F
Abstract
The structure of the 24F nucleus has been studied at GANIL using the β decay of 24O and the in-beam γ-ray spectroscopy from the fragmentation of projectile nuclei. Combining these complementary experimental techniques, the level scheme of 24F has been constructed up to 3.6 Mev by means of particle-γ and particle-γγ 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.
