Abstract

fetched live from OpenAlex

In an effort to explore computational methods to investigate resonances in atomic systems involving positrons, we present a calculation of resonances in positronium–hydrogen scattering, using the stabilization method. The density of resonance states is calculated using extensive Hylleraas-type wavefunctions. Resonance energies and widths for three S, two P, and two D states are determined, from the stabilization plots of the density of resonance states. Our results, obtained by using a real algorithm, are in good agreement with those obtained by using the method of complex-coordinate rotation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
