The structure of the $^{24}\mathrm{F}$ nucleus has been studied at GANIL using the $\ensuremath{\beta}$ decay of $^{24}\mathrm{O}$ and the in-beam $\ensuremath{\gamma}$-ray spectroscopy from the fragmentation of $^{27,28}\mathrm{Na},^{25,26}\mathrm{Ne},$ and $^{29,30}\mathrm{Mg}$ nuclei. Combining these complementary experimental techniques, the level scheme of $^{24}\mathrm{F}$ has been constructed up to $3.6\phantom{\rule{0.28em}{0ex}}\text{MeV}$ by means of particle-$\ensuremath{\gamma}$ and particle-$\ensuremath{\gamma}\ensuremath{\gamma}$ 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.
