Abstract
The nuclear reactions $^{12}\mathrm{C}(^{12}\mathrm{C},\ensuremath{\alpha})^{20}\mathrm{Ne}$, $^{12}\mathrm{C}(^{12}\mathrm{C},p)^{23}\mathrm{Na}$, and $^{12}\mathrm{C}(^{12}\mathrm{C},n)^{23}\mathrm{Mg}$ are the primary reactions in carbon burning, which occurs as part of several stellar processes. The Gamow window, which describes the energy range where most of these reactions take place, is typically around 1.5 MeV in the center-of-mass frame. Direct measurements of the cross sections at this energy are difficult due to the large Coulomb barrier present between the carbon nuclei; however, a successful surrogate measurement can provide the branching ratios between these reactions while avoiding the $^{12}\mathrm{C}+\phantom{\rule{0.16em}{0ex}}^{12}\mathrm{C}$ Coulomb barrier. An experiment was performed using inelastic scattering of 40 MeV $\ensuremath{\alpha}$ particles on $^{24}\mathrm{Mg}$ as a possible surrogate for the $^{12}\mathrm{C}+\phantom{\rule{0.16em}{0ex}}^{12}\mathrm{C}$ compound nucleus.

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.
