Bibliographic record
Abstract
Excited states have been populated in ${}^{108}\mathrm{In}$ and ${}^{110}\mathrm{In}$ in complementary backed- and thin-target experiments using the Stony Brook and the $8\ensuremath{\pi}\mathrm{Ge}$-detector arrays. The level schemes for both isotopes have been extended and modified, including the first observation of $\ensuremath{\Delta}I=2$ bands in ${}^{110}\mathrm{In}.$ Lifetimes of states in four $\ensuremath{\Delta}I=1$ bands and one $\ensuremath{\Delta}I=2$ band have been measured using the Doppler-shift attenuation method. Experimental total angular momenta and reduced transition strengths for the $\ensuremath{\Delta}I=1$ bands have been compared with tilted axis cranking predictions for shears bands with configurations involving one proton ${g}_{9/2}$ hole and one or three valence quasineutrons from the ${h}_{11/2}$ and ${g}_{7/2}{/d}_{5/2}$ orbitals. The $\ensuremath{\Delta}I=2$ bands have been compared with principal axis cranking predictions for configurations with two ${g}_{9/2}$ proton holes and a ${g}_{7/2}$ or ${d}_{5/2}$ proton and one- or three-quasineutron configurations involving the ${h}_{11/2}$ and ${g}_{7/2}{/d}_{5/2}$ orbitals. In general, there is good overall agreement for both the angular momenta and reduced transition strengths. The $\ensuremath{\Delta}I=1$ and $\ensuremath{\Delta}I=2$ bands have large ${\mathcal{J}}^{(2)}/B(E2)$ ratios as expected for the shears mechanism. The $B(M1)$ strengths deduced for the $\ensuremath{\Delta}I=1$ bands show a decreasing trend as a function of spin, which is also a feature of the shears mechanism. Configuration assignments have been made for most observed bands based on comparisons with theory and systematics of neighboring nuclei.

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.
