Abstract

fetched live from OpenAlex

The results of high-precision variational calculations are reported for a number of bound states in various Coulomb three-body systems, including helium and helium-muonic atoms, some adiabatic systems (H2+, D 2+ and DT+ ions) and muonic molecular ions ppμ, ddμ, ttμ and dtμ. The hyperfine splittings for the double electron-excited states in the helium-muonic 3He2+ μ−e− and 4He2+ μ−e− atoms have also been determined. The results of this study are significantly more accurate than results known from earlier calculations for all considered systems and states. The approach can be used to determine the bound-state spectra in various three-body systems to arbitrary high accuracy. We also discuss a number of complications which are usually detected in high-precision bound-state calculations of few-body systems.

Full frame distilled prediction

Teacher imitation

Not 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.
