Study of Astrophysically Important Excited States of 30S via the 28Si(3He,n\gamma )30S
Bibliographic record
Abstract
The 29 P(p, ) 30 S reaction rate strongly affects explosive hydrogen burning in classical novae and type I X-ray bursts, and depends on the structure of proton unbound 30 S states. The rate in the temperature characteristic of nucleosynthesis in novae and X-ray bursts had been previously predicted to be dominated by two low-lying, unobserved, J = 3 + and 2 + resonances above the proton threshold in 30 S. Since then, two states have been found at 4699(6) keV and 4814(3) keV, which were tentatively assigned to be the 3 + and 2 + states, respectively. To confirm the existence of these two levels and their energies, the structure of 30 S was investigated via an in-beam -ray spectroscopy experiment using the 28 Si( 3 He, n) 30 S reaction at University of Tsukuba Tandem Accelerator Complex in Japan. This work describes the experimental setup and presents the preliminary results.

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.
