Abstract
Abstract\nTwo rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus 57 Ni. These bands complete the systematics of well- and superdeformed rotational bands in the light nickel isotopes starting from doubly-magic 56 Ni to 60 Ni. High-spin states in 57 Ni have been produced in the fusion-evaporation reaction 28 Si(32 S, 2p1n) 57 Ni and studied with the ?-ray detection array Gammasphere operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in 57 Ni are compared to those of neighbouring isotopes and interpreted by means of configurationdependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g 9/2 proton and one 1g 9/2 neutron, resulting in an unambiguous understanding of the energetically favoured signature ? = ?1/2 band but a somewhat less satisfactory description of the signature ? = +1/2 band.

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 it
