Cross Section Measurements for the Nucleosynthesis of Heavy Nuclei and Type Ia Supernovae \n
Bibliographic record
Abstract
In this work, two rather different experiments with their respective analysis have been described. The first experiment concerned the 20Ne(d,p)21 Ne transfer reaction and the second the 12 C+12C fusion reaction. \nAn experiment of 20 Ne(d,p)21 Ne transfer reaction was performed in Munich, Germany using the Quadrupole Dipole Dipole Dipole (Q3D) magnetic spectrograph. This experiment has aimed at the investigation of spectroscopic information around the Gamow window of the 17O(α,γ)21 Ne located between Ex = 7.65-8.05 MeV. The stated experiment was performed using an 21Ne implanted target on carbon and covered the excitation energies varying from 6.9 MeV to 8.5 MeV. Sixteen states were identified, three of which, \nthe 8.328(6) MeV, 6.977(17) MeV and 6.960(2) MeV have first been observed in this work. \nWithin the Gamow window however, only one state, the 7.955(2) MeV by correspondence to the 7.9603(10) Mev as recorded in literature, has been identified. Out the sixteen states, this work made eleven firm assignments and two “tentative” assignments. \nThe 12 C+12 C fusion reaction was performed at TRIUMF, Canada using TUDA, the TRIUMF UK Detector Array. The experiment covered the centre of mass located between 3.4 to 4.02 MeV. The aim of this work was the determination of the cross section, which would help, at theses energies, reduce uncertainties observed in present data sets. \nAnalysis such ADCs and TDCs calibrations, different cuts selection necessary for particle identification are presented. \n

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.
