Isotopic Effects in the Laser Control of Dissociative Ionization at High Intensities: Role of Permanent Dipole Moments<sup>†</sup>
Bibliographic record
Abstract
Exact (non-Born−Oppenheimer) numerical solutions of the time-dependent Schrödinger equation for a 1-D model of the one-electron isotopomer systems H 2 +, HD +, and HT + have been obtained in a two-color laser control scheme, ω + 2ω, of dissociation and dissociative ionization in the high-intensity ( I ≥ 10 13 W/cm 2 ), nonlinear, nonperturbative regime of laser−molecule interaction. Calculations have been performed at the fundamental wavelengths λ CO 2 = 10.3 μm and λ YAG = 1.064 μm in combination with their second harmonics in order to study the effect of laser frequency and permanent dipole moments on the electron−nuclear dynamics in the presence of periodic asymmetric fields. It is found that asymmetries occur in both the ionization and the dissociation. The phase sensitivity is shown to be quite different in the two wavelength regimes. Adiabatic and nonadiabatic quasistatic models of the dissociation and ionization processes are shown to offer simple interpretation of the calculated asymmetries in terms of tunnel ing ionization and barrier suppression dissociation.

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.
