Abstract
Beta-delayed-neutron ($\ensuremath{\beta}n$) spectroscopy was performed using the Beta-decay Paul Trap and an array of radiation detectors. The $\ensuremath{\beta}n$ branching ratios and energy spectra for $^{135,136}\mathrm{Sb}$ and $^{140}\mathrm{I}$ were obtained by measuring the time of flight of recoil ions emerging from the trapped ion cloud. These nuclei are located at the edge of an isotopic region identified as having $\ensuremath{\beta}n$ branching ratios that impact the $r$-process abundance pattern around the $A\ensuremath{\approx}130$ peak. For $^{135,136}\mathrm{Sb}$ and $^{140}\mathrm{I}, \ensuremath{\beta}n$ branching ratios of $14.6(13)%, 17.6(29)%$, and $7.6(28)%$ were determined, respectively. The $\ensuremath{\beta}n$ energy spectra obtained for $^{135}\mathrm{Sb}$ and $^{140}\mathrm{I}$ are compared with results from direct neutron measurements, and the $\ensuremath{\beta}n$ energy spectrum for $^{136}\mathrm{Sb}$ has been measured for the first time.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
