Electron impact coherence parameters for superelastic transitions terminating on the (…6s6p<sup>1</sup>P<sub>1</sub>) level of the barium atom
Bibliographic record
Abstract
We have investigated inelastic electron scattering from the laser-excited (...6s6p 1P1) state of barium at 20 eV incident electron energy and scattering angles of 5.5°, 9°, 13° and 16°. Laser excitation with linearly polarized light allowed us to extract P1 and P2 Stokes parameters and the λ parameter for the time-inverse related de-excitations X → (...6s6p 1P1) with X = (...6s7p 1P1), (...6s6d 1D2), (...6s7s 1S0), (...5d2 3P2) and (...5d2 1D2 + ...5d6p 1D2). In combination with previously measured values of the P3 Stokes parameter (Johnson P V, Zetner P W, Fursa D and Bray I 2002 Phys. Rev. A 66 22707), we are able to present the set of natural parameters {γ, P+lin, h, P+} for these de-excitations. Comparison of the experimental results with theoretical results calculated in the convergent close coupling formalism is made.

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.
