Abstract
The structure of the nucleus has been studied at GANIL using the decay of and the in-beam -ray spectroscopy from the fragmentation of and nuclei. Combining these complementary experimental techniques, the level scheme of has been constructed up to by means of particle- and particle- 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.
