Abstract
The $\ensuremath{\beta}$ decay of $^{11}\mathrm{Li}$ has been investigated at TRIUMF-ISAC using a high-efficiency array of Compton suppressed $\mathrm{HPGe}$ detectors. From a line-shape analysis of the Doppler-broadened peaks observed in the $^{10}\mathrm{Be}$ $\ensuremath{\gamma}$ spectrum, both the half-lives of states in $^{10}\mathrm{Be}$ and the energies of the $\ensuremath{\beta}$-delayed neutrons feeding those states were obtained. Furthermore, it was possible to determine the excitation energies of the parent states in $^{11}\mathrm{B}\mathrm{e}$ with uncertainties comparable to those obtained from neutron spectroscopy experiments. These data suggest that the $\ensuremath{\beta}$ decay to the $8.81\phantom{\rule{0.3em}{0ex}}\mathrm{MeV}$ state in $^{11}\mathrm{Be}$ occurs in the $^{9}\mathrm{Li}$ core and that one neutron comprising the halo of $^{11}\mathrm{Li}$ survives in a halolike configuration after the $\ensuremath{\beta}$-delayed neutron emission from this level.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
