Paramagnetic defects in neutron-irradiated α-quartz: Novel Al-associated E’ centers
Bibliographic record
Abstract
Two new paramagnetic defects ( E 14 ′ and E 16 ′ ) have been revealed in neutron-irradiated natural α -quartz by using electron paramagnetic resonance (EPR) spectroscopy. The EPR spectra of the E 16 ′ center as well as a previously reported but incompletely characterized E 11 ′ center demonstrate that their super-hyperfine structures arise from interaction with 27 Al, the first-ever examples of Al-associated E ′ centers in crystalline quartz. The matrices g and A ( 29 Si ) , A ( 27 Al ) of E 11 , 16 ′ , g and A ( 29 Si ) of the E 14 ′ center, have been determined.

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.
