Tune-out wavelengths for helium-like ions in plasma environments
Bibliographic record
Abstract
We investigate the influence of model plasma environments on the tune-out wavelengths for helium-like ions based on the Debye–Hückel shielding approach to plasma modeling. The dynamic polarizability for the lowest singlet and triplet S-states of the helium-like ions (Z = 3–8) for various screening parameters are calculated using correlated exponential wave functions within the framework of pseudostates summation method. Frequency-dependent polarizability for the 2 3 S state; energies for the 1 1 S → 2 1 P and 2 3 S → 2 3 P transitions; tune-out wavelengths for the 1 1 S and 2 3 S states as functions of screening parameter, are reported. For the unscreened cases, our results are in agreement with the available theoretical and experimental predictions.

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.
