Abstract: Cross sections of $1n$-removal reactions from the neutron-rich nucleus $^{37}\mathrm{Mg}$ on C and Pb targets and the parallel momentum distributions of the $^{37}\mathrm{Mg}$ residues from the C target have been measured at $240\text{ }\text{ }\mathrm{MeV}/\text{nucleon}$. A combined analysis of these distinct nuclear- and Coulomb-dominated reaction data shows that the $^{37}\mathrm{Mg}$ ground state has a small $1n$ separation energy of ${0.22}_{\ensuremath{-}0.09}^{+0.12}\text{ }\text{ }\mathrm{MeV}$ and an appreciable $p$-wave neutron single-particle strength. These results confirm that $^{37}\mathrm{Mg}$ lies near the edge of the ``island of inversion'' and has a sizable $p$-wave neutron halo component, the heaviest such system identified to date.
