Abstract
We report on high-statistics data from the ${\ensuremath{\beta}}^{\ensuremath{-}}$ decay of the $^{46}\mathrm{K}\phantom{\rule{4pt}{0ex}}{J}^{\ensuremath{\pi}}={2}^{\ensuremath{-}}$ ground state taken with the GRIFFIN spectrometer located at the TRIUMF-ISAC facility. In total, 199 $\ensuremath{\gamma}$ rays and 42 excited states were placed in the level scheme, and from the observed $\ensuremath{\beta}$ feeding and angular correlations of pairs of cascading $\ensuremath{\gamma}$ rays, it was possible to assign spins and parities to excited states and determine mixing ratios for selected $\ensuremath{\gamma}$ rays. The level structure of $^{46}\mathrm{Ca}$ is compared to theoretical predictions from a microscopic valence-space Hamiltonian derived from two- and three-nucleon forces. These calculations are in reasonable agreement with the experimental data and indicate that the protons in this region are not as inert as would be expected for semimagic nuclei.

How this classification was reachedexpand
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.
