Abstract
Gamma-ray and conversion-electron spectroscopy have established the existence of a 2.29(1) s, ${K}^{\ensuremath{\pi}}={0}^{+}$, isomeric state in neutron-rich $^{174}\mathrm{Tm}$. The isomer deexcites via 100- and 152-keV electromagnetic transitions. First results from a newly commissioned Si(Li) detector array have established their $M1$ and $E3$ multipolarities, respectively. The single-particle configurations of the excited states suggest that the $E3$ transition originates from a $\ensuremath{\pi}{h}_{11/2}^{\ensuremath{-}1}\ensuremath{\rightarrow}\ensuremath{\pi}{d}_{3/2}$ configuration change, whereas the $M1$ transition occurs between members of a Gallaghar-Moszkowski doublet. From the measured half-life, the deduced $B(E3)$ value of 0.024(2) W.u. is highly hindered. The reported measurements resolve ambiguities in the previously proposed \ensuremath{\beta} decay scheme of $^{174}\mathrm{Er}$ to $^{174}\mathrm{Tm}$.

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.
