Abstract

fetched live from OpenAlex

The cranked Nilsson-Strutinsky formalism is employed to investigate the band structure of $^{115}\mathrm{I}$ from low to high spin. A set of eight rotational bands with well established spins and parities are analyzed. Five bands start at low spin and are assigned to the single-particle proton orbitals $({d}_{5/2},$ ${g}_{7/2}),$ ${g}_{9/2}, \text{and} {h}_{11/2}$, which are close to the Z = 53 Fermi surface for a deformation of ${\ensuremath{\varepsilon}}_{2}=0.2$. The analysis of the observed level energies relative to a rotating liquid drop and spins versus $\ensuremath{\gamma}$-ray energies allow one to track the evolution of the configurations with increasing spin. It is of special interest that one band in the valence space is observed to terminate smoothly at ${I}_{\mathrm{max}}=67/{2}^{+}$.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
