Abstract
Excited states ranging from low to high spin in $^{135}\mathrm{Nd}$ have been investigated using the $^{100}\mathrm{Mo}(^{40}\mathrm{Ar}$, $5n)$ heavy ion fusion evaporation reaction with the JUROGAM II $\ensuremath{\gamma}$-ray spectrometer. In the present work we report a new $17/{2}_{3}^{\ensuremath{-}}$ state and a new band composed of $E2$ transitions at high spin. The configuration assigned to the $17/{2}_{3}^{\ensuremath{-}}$ state is obtained by coupling one neutron in the $1/{2}^{+}[400]$ orbital to the ${8}^{\ensuremath{-}}$ isomer in $^{134}\mathrm{Nd}$ based on the $\ensuremath{\nu}7/{2}^{+}[404]\ensuremath{\bigotimes}9/{2}^{\ensuremath{-}}[514]$ configuration. The deduced ratio of reduced transition probabilities of 2.0(5) from the new $17/{2}_{3}^{\ensuremath{-}}$ state to the $13/{2}_{2}^{\ensuremath{-}}$ and $13/{2}_{1}^{\ensuremath{-}}$ states supports the tilted precession interpretation of the band built on the $13/{2}_{2}^{\ensuremath{-}}$ state, in which, instead of the rotation around the intermediate axis present in the yrast band, the rotation is around the long axis of the intrinsic reference frame. The configuration of the newly observed high-spin band is discussed in the framework of the cranked Nilsson-Strutinsky model. The calculated results provide evidence for large triaxiality of the discussed bands.

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.
