Abstract
A $\ensuremath{\gamma}$-decaying isomeric state (${\ensuremath{\tau}}_{1/2}={197}_{\ensuremath{-}17}^{+19}$ ns) has been identified in $^{96}\mathrm{Cd}$, which is one $\ensuremath{\alpha}$ particle away from the last known bound $N=Z$ nucleus, $^{100}\mathrm{Sn}$. Comparison of the results with shell-model calculations has allowed a tentative experimental level scheme to be deduced and the isomer to be interpreted as a medium-spin negative-parity spin trap based on the coupling of isoscalar ($T=0$) and isovector ($T=1$) neutron-proton pairs. The data also suggest evidence for the population of a ${9}^{+}$ $T=1$ state, which is predicted by shell-model calculations to be yrast. Such a low-lying $T=1$ state, which is unknown in lighter mass even-even self-conjugate nuclei, can also be interpreted in terms of the coupling of $T=0$ and $T=1$ neutron-proton pairs.
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.

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.
