Neutron-scattering studies of the phase transitions in high-pressure ices during annealing
Bibliographic record
Abstract
Inelastic incoherent neutron scattering was used to study the phase transition process of high-density amorphous (HDA) ice to low-density amorphous (LDA) ice by thermal treatment. The results show that when the annealing temperature is lower than 136 K no obvious phase-transition is observed, and transformation of the HDA ice to the LDA ice occurs between 136 and 144 K. From comparison of the measured inelastic neutron-scattering spectra for HDA ice and ice Ih, it is found that the internal interactions (covalent bond OH and three-body interaction HOH) are stronger in HDA ice, which correlates with the longer nearest OO distances in HDA ice compared to ice Ih (2.80 and 2.75 Å, respectively). The report also discusses the differences in vibrational spectra of LDA ices obtained by different methods (annealing HDA ice and depositing water vapour on a cold substrate). PACS No.: 64.60-i

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.
