Atomic properties and transition parameters of highly charged Sb-like isoelectronic ions
Bibliographic record
Abstract
The atomic properties and transition parameters of Sb-like Cs 4+ , Ba 5+ , La 6+ , Ce 7+ , Pr 8+ , Nd 9+ , Pm 10+ , and Sm 11+ ions were first calculated using the GRASP2K package. This method is based on the multi-configuration Dirac–Hartree–Fock (MCDHF) method. In this calculation, the contributions of Breit and QED corrections were taken into consideration. By comparison, our results were in good agreement with the NIST values for Cs 4+ and Ba 5+ , which revealed that our calculations are dependable. Meanwhile, it also showed that these ions have high sensitivity to the fine-structure constant α and long-lived metastable states. In particular, Pm 10+ and Sm 11+ had very long-lived metastable states with transitions within the optical transition. These ions are useful for the research of ultra-accurate atomic clocks and fundamental physics.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
