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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
