Polarization and Momentum Distribution of 23Ne and 25Al Produced in One Nucleon Pickup Reactions at 10A MeV
Bibliographic record
Abstract
We measured the polarization of the β‐emitting 23Ne (Iπ = 5/2+, T1/2 = 37.24 s) and 25Al(Iπ = 5/2+, T1/2 = 7.18 s), produced through the one nucleon pickup reactions in the intermediate energy heavy ion collisions, and was compared with those from the projectile fragmentation process. The larger polarization which seems to persistently be positive throughout the momentum distribution, and sharper momentum distributions suggest nuclear friction mechanism to be responsible for the polarization phenomena. Using such a large polarization, magnetic moment of 23Ne and the quadrupole moment of 25Al were measured. The obtained values are |μ(23Ne)| = 1.0817(9) μN and |Q(25Al)| = (240 ± 20) mb.

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.
