Multi-sideband interference structures by high-order photon-induced continuum-continuum transitions in helium
Bibliographic record
Abstract
Following up on a previous paper on two-color photoionization of <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:mrow><a:mi>Ar</a:mi><a:mo>(</a:mo><a:mn>3</a:mn><a:mi>p</a:mi><a:mo>)</a:mo></a:mrow></a:math> [D. Bharti , ], we present measurements and calculations for a modified three-sideband (3-SB) version of the reconstruction of attosecond beating by interference of two-photon transitions (RABBITT) configuration applied to <b:math xmlns:b="http://www.w3.org/1998/Math/MathML"><b:mrow><b:mi>He</b:mi><b:mo>(</b:mo><b:mn>1</b:mn><b:mi>s</b:mi><b:mo>)</b:mo></b:mrow></b:math>. The 3-SB RABBITT approach allows us to explore interference effects between pathways involving different orders of transitions within the continuum. The relative differences in the retrieved oscillation phases of the three sidebands provide insights into the continuum-continuum transitions. The ground state of helium has zero orbital angular momentum, which simplifies the analysis of oscillation phases and their angle dependence within the three sidebands. We find qualitative agreement between our experimental results and the theoretical predictions for many cases but also observe some significant quantitative discrepancies.

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.
