Abstract
Rotational structures have been measured using the Jurogam II and GAMMASPHERE arrays at low spin following the $^{155}\mathrm{Gd}(\ensuremath{\alpha},2n)^{157}\mathrm{Dy}$ and $^{148}\mathrm{Nd}(^{12}\mathrm{C},5n)^{155}\mathrm{Dy}$ reactions at 25 and 65 MeV, respectively. We report high-$K$ bands, which are conjectured to be the first candidates of a ${K}^{\ensuremath{\pi}}={2}^{+}\ensuremath{\gamma}$ vibrational band, built on the $[505]11/{2}^{\ensuremath{-}}$ neutron orbital, in both odd-$A\phantom{\rule{4pt}{0ex}}^{155,157}\mathrm{Dy}$ isotopes. The coupling of the first excited $K={0}^{+}$ states or the so-called \ensuremath{\beta} vibrational bands at 661 and 676 keV in $^{154}\mathrm{Dy}$ and $^{156}\mathrm{Dy}$ to the $[505]11/{2}^{\ensuremath{-}}$ orbital, to produce a ${K}^{\ensuremath{\pi}}=11/{2}^{\ensuremath{-}}$ band, was not observed in both $^{155}\mathrm{Dy}$ and $^{157}\mathrm{Dy}$, respectively. The implication of these findings on the interpretation of the first excited ${0}^{+}$ states in the core nuclei $^{154}\mathrm{Dy}$ and $^{156}\mathrm{Dy}$ are also discussed.

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.
