Exclusive decay study of the 16.62 MeV (2<sup>-</sup>, T=1) resonance in <sup>12</sup>C
Bibliographic record
Abstract
The 3 alpha decay of the 16.62 MeV (2(-), T = 1) resonance in C-12 has been studied for nearly a century starting with one of the first nuclear reaction studies at the Cavendish Laboratory in the 1930s. In the hitherto latest study published a decade ago a model based on earlier work from the 1960s was found to give a good account of a set of inclusive data. This model describes the decay as an l = 3 alpha-particle populating the 2(+) state of Be-8. Here we provide new exclusive data on the 3 alpha decay of the 16.62 MeV resonance, and demonstrate that the decay is best described by a model with predominantly l = 1 emission with an admixture of l = 3.

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; a candidate call from one teacher head, not a consensus.
