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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
