New E′ centers in neutron-irradiated <i>α</i> -quartz
Bibliographic record
Abstract
Several E′ -type defects have been revealed in neutron-irradiated natural and synthetic α -quartz by using electron paramagnetic resonance (EPR) spectroscopy. For the known E 2 ′ center the primary spin Hamiltonian parameter matrices g and A ( 29 Si) (hyperfine interaction with 29 Si) have been refined and provide compelling evidence for spin trapping on the long-bond Si atom. The EPR spectra of the new E 11 ′ center demonstrate that the super-hyperfine structure arises from the interaction with 27 Al, the first-ever example of Al-associated E′ centers in crystalline quartz. The matrices g and A ( 29 Si) of E 11 ′ and another new center ( E 12 ′ ) support the forward-oriented configuration proposed for the E α ′ center in amorphous silica.

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.
